I was already considering a small whiteboard in my office to track personal projects when 3M sent me a free sample of this product, along with a Dry Erase Accessory Tray. The following is my honest assessment.

Hanging was not difficult since adjustments can be made. I made light pencil marks on the wall so that the surface would be level and followed the instructions provided. The surface smooths out fairly well, but shows every imperfection of the wall as bumps or dimples. It relaxed a bit after hanging requiring a bit more smoothing, but has stabilized.

The surface accepts dry erase marks very nicely from the Expo brand marker I have been using. Cleanup with the provided cloth leaves little 'flakes' of mark behind—my only complaint.

This is a good quality, innovative product that I am happy to use every day.
