I bought the 10 mm many years ago. I found them to be extremely difficult to handle because of the size and the titanium is kind of hard to manipulate. (yes, yes, I do know what titanium is) In any case I did manage to finally get them in myears and they worked just fine. They never have looked the same since then. They became bent and lost the round look and never did properly close again.I keep them around to use at night when I am having some irritation problems ( and practically everything gives my earlobes irritation).I was hoping by now they would have made some improvemnt with the ease of handling. I am not convinced that this has happened. I am still sitting on the fence about buying the 14mm and giving it another try. But please believe me when I tell you the 10 mm are very SMALL. I would not order them.fg
