I bought my wife and myself one of these magnifiers. I kept the one with the bad case. The zipper has missing teeth were you cannot zip it all the way down. If you do you have a hard time unzipping it. It gets stuck because of the missing teeth. It was that way when I received it.
Pros: Good quality magnifier
Cons: Bad case
