I inherited my sister's old Fitbit Flex when she switched to another tracker, and with it the old strap that originally came with her Flex became. I wore it for quite a while until the little yellow rubbery clasp broke. After that I continued to use a bracelet with just a metal pin to hold it on my wrist but it doesn't hold up very well and the whole bracelet flew off my wrist throughout the day. I was looking for replacement bands at Revain and came across these. Based on the reviews I read they seemed good and the price reasonable. While the strips looked good when they arrived and they came with a little black clasp, the metal toothed part of the comb was awful. It doesn't fit well in the straps as they aren't long enough to fully seat in the grooves. The whole metal square came out of the strap just as I was trying to put the strap on my wrist, even with the little rubber clasp that came with the strap. I ended up using my old worn out Fitbit strap and just grabbed the little black rubber clasp to use with my old strap. I'm giving this review 2 stars because the bands themselves look good and I think they would work well if it wasn't for the poor design of the metal part which unfortunately renders these cans unusable. I will order different groups.
