Looks good, quick delivery, good value.
Looks good, quick delivery, good value.
Great for replacing my smartwatch for sleep monitoring or quickly checking the time. The touch-sensitive part is very sensitive and often triggers when doing manual work. Very good battery life for such a small device. The video game mode is fun, the ring turns into a game controller, and some games are quite entertaining. easy-to-set-up and use mobile app. You can adjust the brightness and there are quite a few other options for the ring. A bit big on the finger but not easy to make it smaller.
Everything perfect. It arrived within the agreed time. The ring has quite good quality. It's ideal for getting started with this type of device.
