回答“Can I replace the wrist band of the charge HR?”Okay, so my wife found and purchased a replacement band for her Fitbit. Of course she wants ME to figure out how to put the works into a new band. Which is not working...the small screwdrivers they include with the new band do not remove any screws--they just strip the threads. The box containing the new band had a legend on it which reads: "Please visit this website about product installation, Thanks! www.etoper.com/hr.mp4" The video at this site is in a foreign language, and does nothing to help me understand how to replace the band. I knew I was in trouble when the 'instructions' on the back of the box read like a bad Chinese menu, with misspellings and grammar errors throughout. Sorry, it's a waste of time so far... Bob K.
