Beautiful ceiling! Nicest drop ceiling i’ve ever seen!, only takes about an inch of head room. This product is amazing! It goes up easily and fairly quickly. I finished my den in the basement which is 380 s.f. and everyone comments on the ceiling. The J bars around the parameter provide a finished look – no need for crown moulding. I would have given this product 5 stars; however, the small package that I needed in addition to the 6 large sets I ordered earlier arrived with all of the tile corners bent on one side. I did notice that unlike my first order, the single box of tiles wasn’t bound with extra cardboard. I used the slightly damaged tiles for special cuts so there was no need for replacements. I will be buying this product again when the time comes to finish the rest of my basement 🙂
