Update: Lighter ones change their color even earlier. Each pack of four only lasts 2-4 months depending on the colour, so I won't recommend them. ------ Pros: Looks great. Easy attachment compared to original Fitbit bands. The main reason I chose her. Cons: Hard material. They get dirty in less than a month and are difficult to clean. To be honest I haven't tried many ways to clean them, but the usual ones (e.g. with soap) didn't help. Also, what should fit in the strips doesn't fit in any of the strips. So they're not perfect, but ok.
