I use the device when I ride my electric unicycle and I use EUC world as an android app. It gives me a read out of all of the specifications of the wheel while I’m riding it on my wrist.I do not use it cellularly, so I cannot comment on this. But for what I use it for this watch would be close to perfect. I would give it five stars if it had a USB charging input rather than the cradle, they give you that you’re forced to use. If I could simply plug in a USB cable, I could permanently mount it to my risk guards.

good buy

Wearing the watch is very uncomfortable to wear. I have small wrist and have to over tighten it so that it doesn’t slip too much. Over time i find myself taking the he watch off to give wrist a break. The watch rings when my phone receives call, but cant engage caller or make any outgoing calls. I’m therefore planning on returning watch
