Bests & Worsts Reviews from Amazon

The shape doesn't bother my wrist like a regular watch did, I don't normally wear a watch, now 24/7 after a mini stroke. App on Android Nexus4 disconnects when certain background apps run like keepalive and Discovery which I stop manually to save battery power anyway. Pulse accurate, BP very close to a cuff reading, amazing! It knows when you are sleeping, it knows when you're awake! Bought a spare! First one connected to my old phone which died had to use a new watch with my new phone since they pair only to one phone unless reset loosing in my case 3 months of data. Created a f b group for help since questions here are not exactly interactive. Recommended the V100s to 5 people so far, the WoFIT app works great on my new phone.
