I don't know if it's the same brand, but they use it in the conference rooms at one of the places I work and it's terrible. It's so difficult to clean that they've already repainted after just a couple of months. Now no one is allowed to keep their work on them overnight, and they've banned low-odor markers (apparently those stain more?).

We have it in our office and it works well. I might look into the wallpaper though, we had to plaster the walls first which took a lot of time.

It's way better than a whiteboard though, it's another feeling to be able to draw on the entire wall.

We gave away about 75 cans at our first Swagapalooza conference 18 months ago and I haven't heard any complaints.
