Review on Sophili Bands - Compatible with Fitbit Charge HR and HR1 (Purple/S) - Silicone Replacement Wristband Strap with Metal Buckle for Better Fitness Enhancement by Chris Young

This replacement band worked exactly as described and had all the tools I needed. My old group broke up, now I can use my Charge HR again. The only minor downside was that, as other reviewers have pointed out, the instructions that come with it aren't very clear. I watched a few videos on youtube before disassembling my old one. I have "dark blue" which looks good but it is NOT dark blue. This is a much lighter shade close to the color of the Sam's Club logo. In terms of size, my wrist, measured an inch or two above the wrist, is about the maximum for a small bracelet, or the minimum for a large bracelet. I went with a small and glad I did. It fits very snugly in the third hole, allowing the strap tongue to fit in the last hole. Seems a little thinner and more flexible than my original band but just as strong. I am very happy.
