I was looking for a cup protector for my Kempo martial arts class, we do a lot of kicking and hitting to the groin and a quality cup is definitely needed. I saw this was made of stainless steel and just had to get it... It is definitely better than the 2 cups I already own and unlike some of the other Shock Doctor cups that have the "shock absorption" design which I didn't want since several reviews stated they were not good for kicks as the absorbtion aspect compressed a bit too much on impact.  This is a full cup of steel protecting your important parts so why would anyone not want that between them and a foot?  If you are looking for a cup for martial arts, look no further.
