I bought one this spring. It's a large fridge magnet like you get from realtors, no stronger or thicker. I was expecting something more substantial. Good luck getting the damn thing to fit like I know you want it to. For me it was close but like I was trying to fit the wrong size sheet on my bed. The instructions say to set it out in the sun to get it just right and when I tried to carefully make an adjustment, (there was a pucker that would let in dust and water) it ripped a little. I boxed it up and returned it for an 80% refund. Maybe I'm a moron or they have a good idea that isn't executed quite well enough. Hey...you might love it.
