I'm curious what kind of fortune others have had with their Switcheasy canvas iPad covers. I am now going on my 4th case in only about a months time. It's varied from the corners cracking, to non functioning Velcro, to even receiving new ones with bubbles in the exterior. I'm happy to report that they respond to emails quickly and have almost immediately sent replacements, but I'm about ready to cut my losses and look for something else. How is everyone else's Canvas holding up?
