After seeing this product being offered on the Shark Tank TV show I was intrigued. I've bought one for myself and one as a gift.  The little magnets are very strong and secure.  The item does not stretch or distort your clothing. It is easily transferred to any other clothing item.  It is very well made and should last a lifetime if you don't lose it. In short, a very useful item which I would buy again if I lost the original.
