I blame myself. Having read the many reports criticising the zip on this case, I decided it couldn't be as bad as that, so I went ahead and bought one. I told my wife as I opened the packaging that I would need to be careful because it was meant to be fragile when ,lo and behold ,the little puller came off in my hand. I think it's ridiculous that an item selling at this price has had such a basic design flaw for so long.
