Had them only a few days and I like them so much I signed on to order 2 or 3 more.  My wife said that  should do a search on them first and sure enough I find the exact same product for 2.50 cent less... each.

Anyway, I've never had a problem with Amazon and figure that's the premium you'll pay sometime.

The Croakies work well.  The hold my reading glasses firmly to my face and when I'm not reading the cord is long enough to dangle them around my neck.  So far so good.
