The strap that originally came with the Fitbit was very uncomfortable. It dug into my wrist and left a mark. I ordered another group which was about the same price as all four. It was useless. They barely fit and wouldn't stay in place so I decided to try these. First of all I couldn't believe I got FOUR straps in different colors for the same price! The straps are easily adjustable. Once installed, they remain on the wrist. They're comfortable and stretchy enough that I can remove the Fitbit for charging without having to adjust the strap. While this purchase was cheap, this particular purchase was one of the best buys of the year lol.
