These tiles were exactly what we needed to cover an uneven ceiling. Tiles were easy to trim with a sissor and they adhered easily - we used Loctite. It looks great and was a great buy too. A winner all around.
I love these ceiling tiles. I really shopped around and OS had the best prices by far. They look so good in my tray ceilings. These tiles can be placed in a grid system or directly mounted to ceiling. They were very easy to install. However, you really need to buy the matching grid strips to hide the seams even tho these were directly mounted to the ceiling. Was not able to locate them on OS but was happy they matched coming from another site.
