Good quality. They are a challenge to put up, I used tile adhesive and just did the borders. The ceiling on this rental unit was popcorn and I felt this was the easiest way to get rid of the popcorn ceiling because it was already painted. These tiles saved me a few days if labour with skim mudding as the alternative and less dramatic finish. Tiles really are a conversation piece. Did about 200 sq ft for $400 cdn dollars
