LELO F1S V2 Review: flashy app toy that forgets the basics

I’ve been testing the LELO F1S V2 for a few weeks, and I’ll be blunt: this feels more like a tech demo than a solid everyday toy. On paper, it looks cool – app control, two motors, sonic vibrations, fancy metal shell. In real life, a lot of those things end up getting in the way of just using it and enjoying yourself. I went in expecting a high-end upgrade over basic strokers and sleeves, and instead I got something that constantly reminded me I was using a gadget.

The first impression out of the box is decent: it looks premium, it’s not cheap plastic, and the blue color is nice enough. But once you actually try to use it, you start running into the same issues a lot of Amazon reviewers mention: it’s short inside, there’s no air vent, and you’re fighting the device more than you’re relaxing. If you’re above average or even just solidly average in length and girth, you’re going to notice the limits pretty fast.

Another thing that stood out is how dependent it is on the app. Technically you can use the buttons on the device, but in practice it’s clunky. If you’re not a fan of dragging your phone into everything intimate, this will get annoying. Also, the advertised “high tech” part feels half-baked: the app is usable, but the way modes and patterns work is oddly restricted and not very intuitive. A lot of it feels like it was designed by engineers who don’t actually use the thing.

Overall, my first takeaway is that the LELO F1S V2 is trying hard to look advanced, but it forgets the basics: comfortable fit, simple controls, and natural sensations. If you’re mainly curious about the tech angle, you might have fun playing with the settings for a while. If you just want a reliable, no-drama toy that feels good and works every time, this one is probably going to feel like an expensive experiment.

This is where the F1S V2 really struggles. LELO positions this as a premium, high-tech toy, and the price reflects that. On the LELO site it was around the £180+ mark at one point, and even on Amazon it’s not exactly cheap. For that kind of money, I expect something that feels clearly better than simpler options. Instead, what you get is a device that looks fancy but has basic design flaws: it’s too short for many users, it has no vent, it’s noisy when you move, and the app feels half-finished.

When I compare it to more straightforward toys – like a decent Fleshlight or even mid-range automatic strokers – the value just isn’t there. A Fleshlight plus a basic vibrating ring will often give a more natural, full-length experience for less cash. Even some cheaper suction or piston-style toys actually feel more varied and less robotic. Here you’re basically paying a premium for the LELO name, the metal shell, and an app that’s more gimmick than real upgrade. The 2.3/5 rating on Amazon with over a hundred reviews reflects that; it’s not just one or two people nitpicking.

If this were priced as an experimental gadget around the lower mid-range, I’d say “okay, it’s a quirky toy for tech nerds who like to tinker.” But at this price point, I expect fewer compromises. The fact that you’re advised by other users to “wait for version 3” says a lot – this feels like a V2 that didn’t fix enough of V1’s issues and actually dropped some features like third-party session profiles. In other words, you’re paying more for something that, in some ways, does less than the previous version.

So in terms of value for money, I’d call it poor. It’s not completely useless – it can work, it can make you finish, and some people will like the focused frenulum stimulation. But for the average user who just wants a reliable, comfortable, and fun toy, there are better and cheaper options. Unless you’re specifically curious about the tech aspect and don’t mind the price, this is hard to recommend as a good deal.

The design is probably the strongest first impression of the F1S V2. It looks like a high-end gadget, not a cheap toy. The outer shell is metal, the blue color is decent, and it doesn’t scream “sex toy” at first glance. It’s compact enough to store easily, and it stands up on its own, so you can leave it in a drawer without it rolling around. From a pure aesthetics point of view, LELO did a pretty solid job.

But once you get past the looks and actually try to use it, some design choices start to feel like a problem. The biggest one: the internal length and the rigid shell. The user who measured 9.5 cm to the frenulum contact point is spot on – this is a short toy. If you measure from your frenulum to the base and you’re over that, you’ll be bottoming out on hard metal before your whole length is in. I’m not huge and even I felt like I was constantly at the limit. That’s not exactly relaxing when you’re trying to enjoy yourself.

The second annoying thing is the lack of an air vent. Because the shell is rigid and closed, you get trapped air when you insert. That means extra resistance and a sort of vacuum effect that isn’t really controlled or pleasant. Instead of feeling like gentle suction, it just feels like the toy is fighting you when you try to slide in or move. You can work around it a bit with more lube and slower insertion, but honestly, for this price, they should have solved this with a simple one-way valve or adjustable vent.

The control layout is also not great. You’ve got buttons on the device, but they’re not intuitive enough to use blind, and you quickly realize they expect you to use the app instead. That might be fine for some people, but I’d rather not have to unlock my phone, open an app, and fiddle with sliders mid-session. The overall feeling I got from the design is: looks nice, feels like a prototype in actual use. The basics – length, venting, and simple controls – are not handled as well as they should be.

The battery life on the F1S V2 is okay. I didn’t sit there timing it with a stopwatch, but in normal use I could get several sessions out of a full charge without it dying on me. Charging is done with the included USB cable, and it doesn’t take ages to refill. For a device with two motors and a lot of vibration power, I’d say the battery is pretty solid. You won’t need to charge it after every single use unless you’re going really long.

What bothered me more than the battery was the noise. At low settings, it’s noticeable but manageable, like a mid-range electric toothbrush. As you ramp up the power or start moving more inside the sleeve, the combination of the motors and the trapped air starts making weird, unpleasant sounds. One reviewer compared it to unpleasant noises unless you lie there still, and that matches my experience. If you live with others and need discretion, this is not the quietest option. It’s not jet-engine loud, but it’s definitely not subtle, especially in a quiet room with thin walls.

Using it with the app also means your phone is part of the setup. That’s another layer of battery to think about. I had one session where my phone was low on battery and I ended up stuck on a single pattern because I didn’t want to risk the phone dying mid-use. It’s not the end of the world, but with a toy this expensive, I’d prefer more reliable on-device control so I don’t have to rely on a second gadget’s battery as well.

Overall, I’d rate battery life as fine, no real complaint there. The bigger issue in this area is the noise level and the fact that moving with it tends to make it sound more mechanical and less discreet. If you need something quiet and low-key, there are better options. Here, the power is there, but it comes with a soundtrack that doesn’t really fit the mood.

Comfort is where the F1S V2 really shows its limits. The first problem is the internal length. As mentioned, the main stimulation zone sits around 9.5 cm in, and the shell is rigid. That means if you’re longer than that from frenulum to base, you’re going to be hitting the edge of the device. In practice, that feels like ramming into a metal can. For me, I had to constantly adjust my angle and depth to avoid that, which is the opposite of relaxing. If you’re on the shorter side, you might not have this issue, but anyone average to above average is going to feel cramped.

The second issue is the lack of an air vent. Because the device is sealed, inserting creates a pressure build-up. Instead of a controlled suction effect, you just get resistance and a sort of awkward vacuum that fights your motions. I found myself using more lube than usual just to get in without feeling like I was forcing it. Once inside, any attempt at thrusting tends to create weird noises and more pressure changes, which kills the mood pretty quickly. One Amazon reviewer mentioned that it makes unpleasant noises unless you lie still, and I can confirm that: movement makes it sound more like a noisy gadget than a discreet toy.

The inner sleeve itself isn’t painful or anything, but it’s not particularly comfortable either. It grips fairly tightly, and combined with the localized vibrations, it can go from “interesting” to “too much in one spot” pretty quickly. There’s no way to move the focal point of the inner motor, so if that exact spot isn’t your sweet spot, you’re kind of stuck. I had sessions where it felt okay at first, then quickly turned into an over-stimulated, slightly numb feeling rather than a build-up to orgasm.

Overall, I’d rate comfort as below average for the price. If you lie still, find the right angle, and don’t expect deep strokes, you can get some pleasure out of it. But compared to a softer, vented sleeve or a more adjustable toy, this feels fussy and unforgiving. It’s the kind of toy where you’re constantly aware of the hardware, instead of just zoning out and enjoying the ride.

The F1S V2 uses a mix of silicone and ABS plastic/metal for the outer shell. In hand, it feels solid and not cheap, which is at least in line with the price tag. The outer body doesn’t flex, which is good for durability but bad for adjustability. If you’ve used softer strokers or Fleshlights before, this will feel very rigid in comparison. That’s not necessarily a dealbreaker, but it changes the kind of experience you get – it’s more like a vibrating tube than a soft, squishy sleeve.

The inner sleeve is silicone. It’s not sticky or gross like some cheaper TPE sleeves, and it’s easy enough to clean since the device is waterproof. That’s a plus: I could take it to the sink, rinse with warm water and mild soap, and let it dry. No weird chemical smell out of the box either, which I appreciated. If you’re sensitive to smells, this one is pretty neutral. From a hygiene and maintenance point of view, it’s okay. The material doesn’t feel like it’s going to tear easily with normal use.

Now, in terms of sensation, the sleeve is a bit of a letdown. It’s described as “pliable,” but compared to other toys, it’s not that soft or enveloping. It has some give, but the tightness combined with the closed tube and lack of vent makes it feel more restrictive than pleasurable sometimes. The texture inside is there, but the main thing you feel is the vibration point rather than intricate textures. If you like a more natural, softer grip that you can squeeze or adjust with your hand, this isn’t that kind of toy.

Overall, I’d say the materials are decent but nothing special for the price. The outer shell feels premium, the inner sleeve is okay but not mind-blowing, and the whole thing gives more of a “tech gadget” vibe than a cozy, comfortable stroker. If you’re expecting a super soft, realistic feel, you’ll probably be underwhelmed. If you care more about cleanliness and structure, you might appreciate the build, but you’re still paying a lot for what you get.

Performance-wise, the F1S V2 has power, that’s not the problem. The two motors can hit pretty high intensities, and the sonic-style vibration on the frenulum area is noticeable. When you first turn it on and play with the manual mode in the app, it’s kind of cool to feel how the two motors interact. You can set different patterns for each motor and adjust speeds independently in manual mode, which gives you some room to experiment. If you’re into tweaking settings and finding your own combo, there’s some fun to be had there.

The issue for me is that the stimulation is very focused on one small area and doesn’t move. There’s no way to shift the vibration point or have the toy simulate movement along the shaft. Everything is happening in that same 9.5 cm zone. After a few minutes, it stops feeling exciting and starts feeling repetitive and a bit numbing. One Amazon reviewer called it “robotic,” and I agree. You’re basically getting the same intense buzzing in the same spot over and over. If the app allowed for more complex patterns with randomness or gradual movement effects, it could be more natural, but it doesn’t.

The programmable patterns are also more limited than the marketing suggests. You can program which pattern each motor uses and the starting speed, but you can’t add randomness, and you can’t change the relative motor speeds dynamically once you’re in a programmed mode. On top of that, switching between programmed patterns in the app is clunky: you have to stop the device, select another pattern, and restart. That kills any smooth build-up you might want. For something sold as high-tech, this feels half-finished.

In terms of actual orgasms: yes, it can get you there, but it’s not the most satisfying way compared to simpler toys. I had sessions where I finished, but it felt more like I forced it than naturally built up. Other times I just got bored of the same sensation and switched back to a basic sleeve. If you’re very specific about frenulum-focused, intense vibration, you might appreciate what it does. For general use, I’d say performance is passable but not impressive, especially when you remember the price and the 2.3/5 average rating from other users.

On paper, the LELO F1S V2 is a “smart” male masturbator with two motors, so‑called SenSonic technology, and app control. The idea is that one motor gives regular vibrations and the other sends sonic waves aimed at the frenulum area. You get four built-in patterns plus four user-programmable patterns through the app. It’s waterproof, charges via USB, and has a firm outer metal shell with a soft inner sleeve. That’s the sales pitch, anyway.

In the box, you basically get the device, a USB charging cable, a bit of documentation, and that’s it. No big extras, no sample lube in my case, nothing fancy beyond the usual LELO style. The unit is relatively compact and light (about 284 g), so it doesn’t feel like a brick in your hand. The product page talks a lot about the redesigned app and a retro arcade game that reacts to your strokes, which sounds fun, but in reality it’s more of a gimmick you try once and forget. After a couple of sessions, I stopped caring about the game completely.

One thing to know: this is not a deep stroker or a full-size sleeve like a Fleshlight. It’s more of a short can-shaped device focused on stimulating a specific area about 9.5 cm in. If you were expecting full shaft coverage or something that mimics penetration length, this isn’t it. You basically slide in, hit that specific zone, and that’s where all the action is concentrated. For some people that might be enough, but it’s important to understand what you’re buying before dropping this kind of money.

So in terms of presentation, it sells itself as a high-tech masturbation lab, with sensors, patterns, and an app to tweak everything. In daily use though, it boils down to: a short, enclosed sleeve with strong but very localized vibrations that you mostly have to drive from your phone. If that sounds more like work than fun, you’re already getting the idea of how this feels in practice.
