Review on Delysia King 2-Pack Corner Shower Caddy Bathroom Shelf Wall Mounted Organization and Storage Adhesive Shelves, No Drilling - Black by Mike Morris

Easy to apply (took 15 minutes), strong, good adhesion, lots of space. I ordered two sets as we used to have four shelves and needed extra space. Before that we had a shelf with a tension rod that caused our ceiling panel to come open at the seams. Definitely recommend these shelves. Didn't expect it to last long but well done. Follow the installation instructions carefully! Note: Doesn't work on non-square tiles. Hence the gap in my placement. The glue came off slightly when I realized it wouldn't work after a few minutes and I had plenty of extra glue to try again (twice more).
