Speaking of "cheaper bands" I don't think you could get a much cheaper band than on the Charge HR.
As evinced by myself and many people in this thread alone, you'd better buy yourself some Gorilla Glue if you're buying a Charge HR, because the band is useless, to the point of being "not fit for purpose". Not that FitBit will accept a return, of course...
"We can give you 25% off a new FitBit!" hahaha. No. I'll lament my purchase, apply more glue to keep the band even slightly attached, until it finally gives up the ghost, and then I'll never buy another FitBit product again.
