Broke less than a month
I wanted to love this thing, I really did. It felt more robust to me than the original flex band.  But due to poor workmanship the band split where the translucent part meets the rubber part the third time I took the device out for charging.  I have it superglued together, but who knows how long I will trust that.  Don't really want to lose $100 device because I bought a busted knockoff band.  Pity, I wanted to buy a bunch of different colors, but not if they don't last more than a month.
