LELO might be known for its luxury G-spot vibrators, but the company has entered the market of toys for penises with two offerings; the F1s Prototype and the F1s Reds. These toys are pretty similar, however. So here's what you need to know when deciding between them.
Silicone Sleeve
It's understandable if you can't tell one masturbator from the other. They both come in sleek aluminum cases that will look gorgeous on or in any nightstand! The inner sleeve is made from body-safe silicone that's ribbed for your pleasure. This silicone of the F1s Prototype is black, while the Developer's Kit RED has, as you'd guess, a red silicone sleeve.
SenSonic™ Technology
Functionally, both of these sex toys use sonic pulses, which LELO calls SenSonic™ Technology to create pleasurable sensations rather than vibration. This makes these new toys similar to air pulse toys such as LELO's Sona that have been making waves over the last several years. Of course, it also vibrates, so you get the best of both worlds. Like the Sona, these masturbators have a "Cruise Control" feature that ensures the sonic pulses remain powerful no matter how vigorously you thrust into the toy.
Software Developer's Kit
These toys don't just differ from other strokers because of the sonic sensations. The toys pair with an app for either iOS or Android that tracks everything from how long you use the toy to how hard you were during use. The F1s masturbators accomplish this via a network of sensors in the toy itself. Another futuristic option is the ability to program the toy thanks to LELO providing access to the software developer's kit. Through programming and the sensors, you can create a sex toy that's 100% unique to you! Of course, you don't have to program your own sex toy, but it's sure cool that you can, right? Programmers out there, here's to you!
See through or No See Through?
You can easily tell the difference between the Developer’s Kit RED and the F1s Prototype by appearance. The former has a window in the case that lets you see what's going on as you use the sex toy. You'll see the motion of the sleeve as you thrust, and sonic waves wash over it. So if you're visual or a voyeur, you might prefer it over the F1s Prototype. Either will feel fantastic and introduce you to new sensations, however. This is the only main difference between the two F1s.
Once you choose either the F1s Developer's Kit RED or the Prototype, LELO advises that you use plenty of lubricant because it's quite a snug fit. Thanks to some ingenious designing, you can use the F1s one-handed for up to two hours at a time.
LELO advertises a more powerful and longer orgasm with either F1s than other masturbators, but you will have to try it to see!
