Big upgrade from my original drop in tiles! The tiles are very light weight, which worked for my room, but would not help with insulation if that matters to you. Only negative was the difficulty of cutting without cracking- I used my original grid and had to cut many tiles due to the layout. I notched out tiles so they would lay flat against the grid. Someone let me borrow some big sheers they use for house siding and it went 100% more smoothly. If you have to do a lot of cutting for your room, get your hands on that tool! Love the way they turned out in the end!
