Lelo claims that the Lelo Sona (clitoral stimulator for women) is the best-selling sex toy of all time. And while I don’t know about that – and I’ve obviously not tried it (it’s for women) I’ll take their word for it. But why am I even talking about this? Because the F1s uses the same sonic technology that made the Sona famous. The LELO F1s is probably the best, most high-tech masturbation sleeve around. The sleek device houses an array of orgasm-inducing features such as two motors, heating, 10 sensors and, best of all, LELO’s SenSonic technology. This SenSonic tech upgrades the standard vibrating masturbator with sonic wave pulses that stimulate your whole member instead of individual nerve endings. This tech, along with a ribbed interior, combine to create a truly impressive sensation. While you can learn more about the diameter of the LELO F1S Developer’s Kit SexTech items elsewhere, I need to point out that these items, like other masturbation sleeves for men that you should be hard, or at least semi hard before inserting your penis – so that’s just what I did. The Demo app was launched in 2019 and it was quite a raw beta version. Lelo has made some improvement for the app. Now, it has an officIal version, called "LELO F1S". In all fairness, I’m not too sure how I feel about this. The non-removable sleeve, I mean, like the rest of it, is pretty standard for silicone sex toys since keeping them as clean as possible is the best way to prevent irritation–which can sometimes lead to nasty infections.

Plus, if interactivity is your cup of tea, they have an Open-Interface Performance Console for anyone eager to combine their F1SV2 with a favorite game or video for an extra-added level of erotic immersion. For the ultimate high-end sex party, take it one step further and treat yourself to a hot tub at home. What the hell, while you're at it, throw in some sex furniture too. You deserve it. How to Clean Your LELO Sex Toy I also brought up an issue in my cons: the F1SV2 is a bit on the short side, with its interior length coming in at barely four inches.The sleeve is made of body-safe silicone but I honestly find it rough. It could be more stretchy and “gentle” so to say. Also, there are a ton of sensors all around the toy that measure vibration, temperature, pressure and whatnot. It’s really nice of Lelo to try to push boundaries with all this data but for me it was useless. Maybe those who want to develop custom apps for F1s will find it more usable. Once you’ve finished the device is easy to clean. It’s fully waterproof and they provide a cleaning spray in the kit to keep it pristine.

With the app, It's possible more choices for what kind of sensation to use - only squeezing, only vibration or both. This vibrating masturbation sleeve from Satisfyer bumps up realism with one clever upgrade: heat. The device features three levels of warmth up to 104 degrees Fahrenheit (don’t worry, it’s safe) for a comfortable, realistic feel. It also boasts 10 vibrating functions and seven speeds, plus a waterproof build for use in the shower or tub. USB recharging makes the Satisfyer easy to use, and an hour of active playtime should be enough for almost any session. It’s on the small side at 5.5 inches long, making it quite discreet although not ideal for well-endowed gents. Both motors have 15 intensity settings so this brings tons of variations you can try. The manual interface doesn’t allow for separate control of the motors so you’ll need to use an app for that. Most stroker toys are simply a soft sleeve to upgrade your oft-used hand. This is great, but the Satisfyer takes things up a notch. Squeeze the sides, and the stroker fills with air pressure for a tightening sensation. The inside is made of Cyberskin, a super soft, ribbed material that’s also easy to clean. If you’re new to sex toys, this is a great introduction.First of all, F1s is extremely portable. As you can see from the image below, it’s smaller than Tenga Flip Zero EV and way smaller than Lovense Max 2. If power is what you’re looking for in a sleeve masturbator, the F1SV2 may be what you’ve been waiting for, as its turbocharge feature significantly boosts the toy’s overall intensity.
