This is a camera bag with a simple concept. They are thin and light. They seem to slide easily and stay closed or open with no problem. I've used two of these on different computers and both work fine. You have to align the hole very carefully not to block any of the cameras. Haven't tried taking them off yet, so I'm not sure if they leave marks or are difficult to remove. I'd suggest the sliding part comes out right away, but the part that's stuck can be more difficult to remove. I often use my webcams for meetings and they are perfect.
