Part that broke was the cheapest part to the device, open/close zipper guide. 1/16th inch metal guide for zipper broke about 4 hrs into weekend trip. Three snaps to open and close the case would replace "el=cheapo" easy to foul, hard to keep clean and use zipper. Design of case puts the greatest load of the case directly on the lenses of the $600.00 glasses. Need to replace zipper with 4-5 1/2" snappers.
Pros: Price
Cons: Lasted 4 hours (open close 5-8 times) before broke
