I received the iFIX It Pro mat, defective for Christmas. Contacted them, they replaced it, second was defective in the same way. I generally only give companies 2 tries to get it right..so that was it.This Delcast mat is by comparison, really great. Very similar to the iFixIt mat in terms of quality (aside from the whiteboard coating). A little bit thicker than the iFixIt mat, which I like, a little bigger (half the price!).I'm not having an issue wit how magnetic it is, folks have complained about that. The thing says for Laptop, SmartPhone...I think if you're using it to take apart something with bigger screws, you're going to be disappointed, but it wasn't designed for that. It is less magnetic than the iFixIt, but only slightly. I could mount this on the wall, and it would hold most of the small screws I stuck to it. Rubber bottom, no slip! Yes. Very nice, put it on your desk, and it won't slide around. Pretty cool. I always use to joke that there were always some screws left over...not anymore. Everything is well thought out and nicely designed, and the product feels high quality.The whiteboard part works very well, but the pen is not as good (as iFixIt's Staedler). The delcast pen has really thick tips (no eraser either). Just buy a Staedler whiteboard marker...nice fine point with an eraser.
