Love the quality - they lay nice and flat. The tabs for bottom work great - great protection for my furniture tops.
cut a hole in the ceiling for a speaker, but a tad too much-which meant I needed a goof-ring. I had no success finding the size ring I needed, until I found 1800ceiling's website that offers custom sized rings. Material is good and delivery was quick. good find
