This morning, my Fitbit Charge 3 band broke at the buckle. But getting it replaced under warranty was an even worse experience.
Look, I get it: Fitbit straps---like all fitness band straps---must break at an alarming rate. And replacements are cheap: I can buy three third-party Charge 3 bands on Amazon.com for less than $7 (!). But the problem with this sort of thing is that you never think to have extra bands waiting for the inevitable. So when one does break, you need the replacement immediately.
