BLACK FRIDAY & CYBER MONDAY 2019 SALES UPDATES: Lelo F1s Kit is currently 20% off (if ordered from the official site).

I’ve been looking for a good male masturbator since many years ago. So, when Lelo launched its F1s, it caught my attention. After giving this toy some trials, I am here to share my reviews with you.

What are the differences between Lelo F1s Developer’s Kit Red and Lelo F1s Prototype? The only difference that the F1s Developer Kit has from the F1s Prototype is that it includes a transparent window. You can see yourself using it, which adds another visual dimension to the overall experience. It is great because you can see how it works thoroughly.

Therefore, most of the points I’ll mention in this review apply to both of the toys.

What is Lelo F1s Developer’s Kit Red?

To put it simply, Lelo F1s is a male masturbator. But not merely a masturbator. It is a male masturbator with 10 cutting-edge performance censors that gives you a hyper-realistic feel at 63 sonic waves per second.

You must be wondering what are sonic waves? It’s the same principle that Lelo Sona Cruise clitoral stimulator applies. Instead of conventional vibrations, F1s uses specialized dual motors to create sonic waves, so it feels like standing in front of a powerful speaker, you can feel it throughout your body, or in this case, your penis. 

The mentioned Cruise Control is also something that is exclusive to Lelo and that no other competitor (e.g. Fleshlight) has.

The F1s also connects to your Smartphone so you can enjoy apps, including the LELO-developed app, games, VR and AR and videos, and build your own. It can also be used on its own, without the app. 

Besides, it’s possible to control the Lelo F1s Red from a distance, and it can connect to your phone through Bluetooth. Talking about partner play; The F1s Red has a window, allowing the user and partner to see it in action inside for a sexy new visual dimension.  For example, your partner can take your phone and control the F1s for you. 

Note: The reason it is called “Developer Kit” is because there will later come an app where you will be able to “develop” your new vibration patterns and settings. Please note that this will be possible with the F1 prototype as well! So, I think the name is just for marketing use.

Key Features of Lelo F1s Developer’s Kit

1. Perfect Size & Ideal Elasticity

Lelo F1s measures about 5.5 inches (143mm) in total length and about 2.8 inches (71mm) in circumference. It has an insertable length of just under 4.5 inches (111 mm).

The insertable part has a strong elasticity – the F1s’ silicone sleeve has a depth of 4.5 inches (11 cm) & a diameter of 2 inches (5cm). This means that your entire penis can be wrapped for stimulation.

2. Premium Materials Guarantees Saftey and Comfort

The silicone sleeve is enclosed in an ABS and aluminum alloy casing. All of these materials are completely body-safe. They do not contain phthalates or any other harmful chemicals, so you don’t have to worry about any material-related allergy breakouts when using the F1s.

Besides, the ultra-smooth silicone sleeve is shaped to fit like a glove and features curved internal grooves in all the right places.

3. Unique Stimulation From “Cruise Control” and “Sensonic Technology”

Sensetouch Technology allows vibrations to start on contact with the skin before building smoothly to stimulate tissue at different levels, thus stimulating professional massage techniques and many toys on the market experience a decline in intensity when they are being pressed against your body.

This is where the Cruise Control feature comes into play and what makes this item so special. When it’s pressed hard against your body it won’t drop its power, which will keep the intensity consistent automatically.

4. Dual Motors for Multiplied Pleasure

F1s uses dual motors to create its signature SenSonic technology. One motor emits sonic waves that permeate deep into your penis, while the other powers the device sensors and delivers conventional vibrations that combine with the sonic waves for an entirely new sensation.

At this point, you must be wondering how do sonic waves and vibrations feel like? It’s easy to understand vibrations, which is a type of high-frequency movement that will provide deep tissue stimulation. Comparing to conventional vibrations, the specialized motor for sonic waves feels like standing in front of a powerful speaker, you can feel it throughout your body.

5. Light Yet Effective

F1s is the lightest male masturbator I’ve ever owned. It weighs only 286.9g (10 oz), which is like holding 3 lemons at hand. Yet, the stimulation from F1s doesn’t compromise. The 10 sensors provide an unbelievably strong experience, making the masturbation process divine and addicting.

6. Long-Lasting Battery

Probably due to its lightness, the battery on F1s is also more lasting than other masturbators.

It will take around 2 hours to finish a full charge and after each charge, the F1s can last continuously 2h even if constantly connected with the app. Besides, this toy can handle 90 days of standby time.

7. 100% Waterproof

The waterproof feature comes handy no matter whether you fancy some wet play or simply want to clean the toy easily.

8. Lock Your F1s to Avoid Unintended Activation

I know some people like to take your sex toys when traveling. I am one of these people. Nothing is more embarrassing than an unintended activation in public.

Whose luggage is buzzing? Yea, mine… The lock function will totally save you from this kind of awkwardness.

How to Use Lelo F1s Red?

There are two ways to use the F1s toy, either 1) directly control the toy with the 3-buttons or 2) connect the F1s for app-controls.

No matter which way you choose, you will need to charge the toy for 2 hours before your first use. The charging is simple, just insert the DC plug into the DC port at the top of your F1s and insert the USB cable on your laptop, voila!

The LED on the interface of your F1s will pulse to indicate it is charging. When it is fully charged the LED will emit a steady glow.

Tips: please only use original chargers provided by LELO with your F1s, otherwise, it may take more than 2 hours to get a full charge, or even damage the devices

Once charged, you may press the power button to activate the toy and you can adjust the intensity to your liking by pressing the + or – buttons. This toy is quite intuitive to use.

If you would like to do the app control. Simply do a long press (around 3 seconds) on the power button to trigger the Bluetooth pairing mode. Once your F1s is successfully paired, you will be able to control the toy and track your performance in real-time with the app

Some More Information About the App/Demo App

There is only a demo version of the app available now. So, what can the App Demo do? You can control the F1s device directly from your smartphone, adjust the intensity, cycle through the modes, and access the exclusive LELO Cruise Control function.

You can also measure progress, speed, and direction while using the toy. Besides, the app can show the statistics of the device and vibrations intensities.

The Developer App has not yet been released. For the release of the developer app, Lelo doesn’t know the exact date yet, unfortunately, but it is in the works.

If you are one of these guys who are into tech stuff, then you can download the SDK and join a community of developers to build the sextech experience of your own. In the developer SDK, you will be able to explore functions such as connecting to VR content. I am not a tech guy, so, I leave you to discover the possibilities.

How to Clean F1s Developer’s Kit?

Since the inside of the F1s is made out of body-safe silicone, it is easy to maintain it. You can use the LELO Toy Cleansing spray to take care of it after every use, and also lukewarm water.

There is no need to use any sort of chemicals that might damage the product. If not getting the spray, you can wash the device with mild soap and water, nothing aggressive.

My Experience with Lelo F1s Developer’s Kit

My girlfriend gave this masturbator to me as a gift because we are in a long-distance relationship and she wants to control the toy with the app from her end. That didn’t work out very well, but I still tried the toy.

To be honest, I wasn’t expecting much from the Lelo F1 because I’ve tried multiple masturbators and none of them actually provided me a truly mind-blowing orgasm. Most male masturbators are bulky and heavy, and it could be tedious to clean after each use.

To my surprise, Lelo F1s is quite different. I am not saying that it’s a perfect toy, but at least it is a lot lighter than any of the other masturbators I’ve tried (e.g. Kiiroo, fleshlight). This is great in my opinion because masturbation finally doesn’t have to feel like weight-lifting!

There are some free lubricant samples that come with the toy, so I grabbed one and applied a generous amount of the lube inside the toy and some on my penis. It was really easy and comfortable to enter. Actually, it was easier and smoother than any other masturbator I’ve used.

There are two types of sensations you can expect from this toy – squeeze and vibration. During my first trial, I didn’t use the app-control. It was really intuitive to use, there are only 3 buttons to choose – power button, + and – buttons.

Once you turn the toy on, both the squeeze and vibration sensations will be activated. Then, all you need to do is to adjust the intensity to your liking. I had my first orgasm with F1s in just 5 minutes and it was really pleasant.

I personally like to have some up and down movements during masturbation, so I only applied the toy to the top half of my penis. For those of you who prefer to cover the entire penis, it’s also possible to do.

As this claims to be an App-controllable masturbator, I decided to give the app a try. There is only a demo app at this moment. It was easy to connect the toy with the app. With the app, you can have more choices for what kind of sensation to use – only squeezing, only vibration or both.

However, I did experience plenty of disconnections while using the app and I don’t even know why it got disconnected. That was a true mood killer. So, I think the demo version is not that good. I am looking forward to having the real version from Lelo.

Besides, I do have a design-related complaint about this toy. I like the design of the F1s toy a lot. It looks simple and modern and functions wonderfully. However, the branding for this toy is way too cheesy in my opinion. There’s a pair of F1-style gloves included in the box. Come on, when would people wear this thing?

Note: I contacted Lelo regarding the connectiivity issue. And they replied, “There should be no connectivity issues at all! and It depends entirely on the bluetooth connection. If you’re having trouble, switch your Bluetooth off and then on again to try reconnecting. Close then restart the LELO app.” I did what they suggested, but still experienced some disconnections.

Review Summary

Related Questions:

When will the F1s toys be launched? The pre-order of F1s was released in early Nov. 2019. All of the pre-orders have been sent out at this moment. Therefore, you can buy this toy at Lelo’s official site at any time now.

When will the Official Developer App be released? For the release of the developer app, Lelo doesn’t know the exact date yet, unfortunately, but it is in the works.

How to lock the F1s? To avoid unintended activation, press and hold the + and – buttons together for 5 seconds to lock your F1s and avoid.

Verdict

Despite some imperfections and the fact that this type of sexual activity will not please everyone, Lelo F1s is pleasant, very well finished and deserve to be purchased.

It’s not easy to tell in advance if you’ll like the styles of F1s as male masturbators, in general, take some time and effort to get used to. However, it is certain that Lelo F1s is positioned among the best in its market and succeeds in the feat of integrating high-tech to male pleasure.
