There is Micarta - (basically the same process of manufacture except using linen instead of fiberglass) This is 2019 and FitBit is still in the business of manufacturing time-limited products.Fitbit Charge 2 will automatically detect certain exercises and record them using our SmartTrack feature which automatically recognizes continuous movement at least 15 minutes in length.

Both of these materials are incredibly strong and resistant to chemicals, etc. There is G10 (fiber-glass soaked in resin, baked and then compressed - knife scales), GFN (glass reinforced nylon - again, knife handle scales). Okay, so you feel those would be too expensive. There is carbon fiber, titanium, magnesium, even aluminum - all of which are able to be CNC machined and made very small and still maintain their integrity. In this day of advanced materials there is no reason to make something like this from cheap plastic. The top section of the weakened side will not resist the pressure / force of the FitBit being attached and then placed on the wrist. One will more than likely be solid and the other will give under gentle pressure and bow downward. Test it with the band off the tracker and slight pressure from your finger. But, the more likely issue is that the top support of the band attachment mount has worn and become broken. The issue? well, as one individual mentioned, it could be the teeny-tiny screw holding the metal bracket to the band. I have been through (4) straps on two different FitBits. Just another way to create a situation in which the customer has to pay for shoddy product design and manufacturing. Yep, most definitely a major design flaw with the attachment portion of the straps.
