First, the color is beautiful, but short-lived. On the first day of wearing, the color rubs off slightly in some places, especially on the magnetic closure. However, he certainly stayed in place and didn't come loose at all, so he has everything he needs. The magnet is strong enough. The second downside is that the mounting grooves on the ends where they snap onto the Fitbit? One was damaged. The other snapped into place with no problems, the other was either bent or something but there was no way to tighten it. Luckily my dad knew a way to fix it and now it works. However, a third disadvantage is that the sides of the strap get caught in the material. I had a new set of satin pillowcases and I usually put my hand under my pillow when I sleep and it would snag and pull on the threads every time I moved my hand. So I wouldn't recommend wearing it with something like satin (or sleeping with it if you have good sheets) or even sweaters. It will only tear them apart.
