The original Fitbit Charge 4 strap broke and is terrible quality, bends etc. This is a great replacement for it - works similar to the apple watch strap and fits pretty well. Didn't know whether to buy small or large, went for the large and it seems to work well - wrist size is just over 7". The bracelet is very good quality and appears to be well made, more expensive than the cheap multi pack floating on the site!hope it lasts long!
