Absolute garbage. Even though the tiles are sticky (and the glue gets all over hands, fingers and other tiles) they don鈥檛 stay down AT ALL. I cleaned and scrubbed my floor before installation. It made no difference. Every corner and many sides are lifting and refusing to stay down. I even ended up trying a heat gun and roller as per one comment suggested. Didn鈥檛 fix it either. These are absolutely not worth the time, money or hassle. I鈥檓 contemplating ripping it all up since it鈥檚 been such a catastrophe.
