Review: Very small product packing a lot of features ! - Delivery overseas was insanely fast. There are a lot of feature, and a lot of possibilities for your security set up. For a basic usage, it is quite fast and intuitive to configure. I appreciate how small it is for a key meant to be left permanently attached to my laptop. The "finger touch" interface works surprisingly well, but could be improved. For Linux, the companion app could be better integrated with the OS for a faster, easier unlocking of the device using pinentry or something... Overall, a complete security solution for a very low price. Not forgetting that this is the only one I found with a backup feature ! I recommend.
Review: Mac/Windows Computer required to Setup! - My Chromebook HAS Chrome OS, but NO official ONLYKEY desktop app available to download! How nice! So to use properly I would have to buy an entire computer, or become a programmer. NOT ALL OF US WANT TO BE PROGRAMMERS!!!! The app available was hacked immediately because this is Open-source, WTF???? I don't wan't NFC, so I got this because I wanted simple, on-device security. I have now wasted over a month and over $100 and still have no security! Thank you for nothing. I was so crushed to be sucked into the "Too Good To Be True" promise of this device.

### ⭐⭐⭐⭐⭐ Very small product packing a lot of features !
*by F***. on April 24, 2023*

Delivery overseas was insanely fast. There are a lot of feature, and a lot of possibilities for your security set up. For a basic usage, it is quite fast and intuitive to configure. I appreciate how small it is for a key meant to be left permanently attached to my laptop. The "finger touch" interface works surprisingly well, but could be improved.

### ⭐ Mac/Windows Computer required to Setup!
*by D***S on May 13, 2025*

### ⭐⭐⭐⭐ The provided keychain can potentially damage your chip. use a circular keyring.
*by J***Y on October 20, 2025*

the little metal piece that connects the loop between the two buttons broke in my pocket. Not the plastic adapter, but the actual blank spot between the two buttons on the chip. it still works fine, but it's a pain to take out of a USB port now. the providede keychain is what broke the piece off, so i don't recommend you use. had it been a circular shaped ring, i don't think it would have broken it. the straight parts on their hook allowed it to slide up at an angle that gained leverage against the flimsy piece of material.
