Love this! The metal is not some cheap junk but quite solid. No drilling or measuring needed, easy to install! Just find the right spot, peel and stick. The adhesive is very strong. The minute it met the surface I knew it was never falling off. As long as you prep the surface correctly(wipe clean, dry), I imagine it’ll stay there forever. I ended up ordering 3 other products! I highly recommend it to anyone who doesn't wanna holes on wall!
