I was impressed by the speed of delivery and quality of product of these glue-up ceiling tiles. They made a beautiful ceiling in our guest bedroom. Previously, the ceiling had been wallpapered over (many years ago before we bought the house). Then it was painted over and over again. The wallpaper was stuck for good and underneath it was cracks in this 120 year old plaster ceiling. Everything was still up so and not falling down so it was just a cosmetic fix. The tiles went up quickly and we used a ceiling tile putty to put them up. We bought that at our local DIY store. The whole project took just a couple of hours. My husband saved the day by making the cuts around the edges with precision. He did this with just a measuring tape, T-square (for a straight edge) and utility knife. It's a perfect way to update an old ceiling especially if you have limited skills and a limited budget.
