I read some negative reviews before ordering. Some people have complained that this strap easily snags on things. However, I decided to give it a try for less than $9. A pleasant surprise was that it didn't discolor my skin. I have very sensitive skin (LoL). Hell, almost any metal will turn my skin green within a few days. It didn't turn my skin a horrible greenish color which is amazing! I also like the ability to adjust the fit with a magnet rather than being limited to using different sizes due to predefined pre-punched holes, which may not work for me. For less than $10, this isn't a problem.
