Sextech company Lelo has launched the Lelo F1s V2, the second generation of its premium penis masturbator device, the Lelo F1s.

The F1s V2 stroker (or ‘pleasure console’ as Lelo calls it) sells for US $219/GBP £195. The company says the new model has double the power of the original, which we reviewed back in 2019.

Fully waterproof and constructed from silicone and aluminium alloy, the device weights 285g and features ten sensors, allowing performance feedback through the Lelo app.

The motors of the F1s V2 emit sonic waves rather than standard vibrations. The technology is branded by Lelo as SenSonic, and is the same tech featured in the company’s popular Sona clitoris stimulator sex toy.

Lelo says that in the F1s V2, these sonic waves “permeate deep into your penis, making it feel as though it’s resonating pleasurable from all directions at once, instead of simply tickling the nerve endings on the surface of your skin.”

One potential literal shortcoming of the original F1s, highlighted in our review, was the device’s insertable length of 4.3 inches, which may not be long enough for some users. The new generation model also has an insertable length of 4.3 inches, and a maximum internal girth width of 5.9 inches.

In a write-up for Lelo’s own blog, an F1s V2 tester acknowledged that, “If you’re extremely girthy this might not be the best penis sex toy for you.” However, Lelo claims that the new model’s sleeve is more pliable than the original’s, making it more comfortable and easier to manoeuvre.

Our 2019 review praised the original F1s’ Cruise Control function, which saves power for moments of deep thrusting to ensure power doesn’t drop when greater pressure is applied. This function is retained in the second generation version.

The F1s V2 can be linked to Lelo’s app, but this linkage is not billed as a core selling point. The device can be controlled with the app, but most users are likely to use the physical control buttons, which doesn’t quite make the most of its tech credentials.

Lelo, which sits alongside products such as the Kiiroo Titan and Kiiroo Keon in the penis stroker market, promises two hours of device usage time between device charges.
