I got ready to replace the broken band with a Fitbit and assembled some jewelry pliers, tweezers, a good light, a magnifying glass and ended up needing none of it. The old strap came loose with a fingernail, and after I scraped the dirt where the strap attached to the FitBit body (phew!), the new one snapped into place with another fingernail. You *need* nails to do this. But it's actually quite simple.
