So easy to install /good quality. I’ve installed peel & stick vinyl tiles before(4 other times). This one was easy since you could use it in any direction (other tiles there is an arrow  and you have to be consistent with the arrow as it’s being laid). This meant that I ended up with extra tiles since I could reuse one tile for the smaller end pieces. I laid it over ceramic tile. I forgot to warm up the tile so my first few pieces I used a laminate/vinyl glue. After the floor warmed up I didn’t use glue except for a piece behind the toilet.  Took me 3 hours to lay this in the bathroom which was approximately 30sq ft. I bought 3 boxes and I have 5 left over tiles. The colors are vibrant. Laid it 2 weeks ago and nothing has popped up.
