Great for low ceiling. Easy to install. I have a 7 foot ceiling and could not afford loosing any headroom. This product was perfect. Easy to install in a square room, in my situation there are many indents and workarounds, everything went well. Called company and they were very helpful. They did not recommend installing LED pot lights (Costco 4″) directly into the tiles, but I did and there are no issues because they are so light.
