LELO F1S Male Masturbator Review

You’ve heard about them for months and now they’re finally here: The LELO F1S SexTech devices! Currently available as the LELO F1S Developer’s Kit RED and the F1S Prototype, they’re finally popping up on review sites and the consensus is that they more than deliver their promised pleasures and that their potential for pushing sex toy technology ahead is endlessly exciting.

The LELO F1S Developer’s Kit RED and the F1S prototype are LELO’s highly anticipated and advanced take on the masturbation sleeve. Where traditional masturbation sleeves only provide surface sensations from little vibrating motors, the F1S series feature LELO’s SenSonic™ technology that delivers deeply penetrating sensation throughout the user’s entire genital region.

In addition to their deep sonic sensations, the F1S series features advanced sensors and includes an app you can use to track your sexual stamina and performance. You can also set your own pleasure patterns, but if you’re technically savvy, you can program the F1S Developer’s Kit RED to do whatever you want. In the near future, expect to see new programs and applications available on the F1S’ included app as developer’s tinker with this new tech. Make sure to bust out your lube for this one. But seriously, apply generously for a fun time.

 If your head is already swimming with possibilities, get some more ideas when you read what some advance reviewers have had to say! 

F1S review

 The F1S Developer’s Kit by LELO: Brand New Amazing Sonic Waves Sex Tech To Explode Your Penis!

“It’s designed to encourage the nerve endings in our cocks to wake the #^@& up. How does some 360-degree stimulation sound? Oh, and it’s called a “Developer’s Kit” for a very good reason: this thing let’s us customize our meat-beating with more precision than anything else I’ve ever seen.”

LELO F1S Review & Test — Is This the Future of Male Masturbators?

“How does it feel? Well, in my opinion, it’s as close to the real thing as a masturbator can get. The combination of silicone ridges, sonic waves, and vibrations encompasses your whole penis and gives it a deep-tissue massage.

However, unlike the real thing, you can fiddle with the intensity to amp up the sensations. Best of all, this isn’t a thrusting masturbator, so there’s no need to move it up and down. It allows for an entirely hands-free play!

Yet, what I loved the most while testing it was that I could not only see how it all works but also MOVE it around. There’s a peeping window you can look through while getting massaged, which actually is a lot hotter than it sounds.”

LELO F1S Review & Test — Is This the Future of Male Masturbators?

“Once you master the controls and figure out what feels best where, it’s fairly easy to control the duration of your experience. This is the best part about this toy: it puts you in the driver’s seat! For me personally, I found that the device was most stimulating when used towards the end of the penis, rather than inserting myself all the way into the device.

Unlike many other male masturbators, this toy is exclusively a vibrator!”

 LELO F1S Developer Kit Review: The Most Advanced Male Toy Ever Made?

“How do you describe a sensation when you have nothing else to compare it to? How do you describe something that feels so good it will bring a tear to your eye?

 The 360-degree Sensonic waves feel so silky smooth as they wash over you, flawlessly engulfing you and pulling out your orgasm from deep down within you. Seriously, you will be surprised that the human body can feel these sensations.

 The ridges on the inside, gently caressing you with every stroke, and the precise sensors that feel like they were made just for you, along with the Cruise control function and the little window you can watch all the action through, all work together to make you feel like the king of the world for a few fantastic minutes.

 You will thank all the gods for this wonderful invention, and marvel at the wonderful times we are living in.”

 The F1S Developer’s Kit Red offers the world’s first sextech platform – but more importantly, it feels incredible!

“Without knowing anything about sonic wave technology, what I can tell you is that it feels like nothing I’ve ever experienced before. And it gets me off so good! And combined with their patented Cruise Control technology, the pleasure waves continue and don’t drop off or waver in any way.

There is something wonderfully erotic about being able to see my cock as it’s getting stroked by a toy. And that’s why I love the hole that’s in the shaft of this toy so you can get a good glimpse of the action happening inside.”

Great product ★★★★★

This little device is quite incredible. At first I wasn’t feeling anything intense and thought it was standard vibrating toy, but then when I started to adjust the two different dial settings I found out what made this one different.
It was intensive and enjoyable and well worth the price of admission!
