I can't say too much in the line of the product because I haven't got to using them yet. I tried them on and they seem to fit well. I can't believe how fast I got them, if I knew I would have got them so fast I would of left myself a day to go diving and try them out. Now I am busy again. As long as they fit how much can go wrong with them.Can't wait to get out there and try them. Thanks for the quick shipment.
