Bought to mount my security doorbell to clear glass and it's still holding up great. I actually had to move the doorbell after it was already there. I used rubbing alcohol and gently tore it off. It seems that under normal conditions it takes a long time to disconnect the doorbell. Just wanted to mention that it adheres well, but it's not the end of the world if you need to move something you've covered in epoxy. It's easy to work with, but remember that after mixing the epoxy and hardener, you won't have much time to work with it before it hardens. The four minutes stated on the packaging are true. I used a bamboo skewer for mixing and used a piece of cardboard as a "palette" so I can just throw them away after use. Another good idea is to fix the item to be glued and then tape it in place to allow the epoxy to cure. But if you have to, you could hold it with your hand, it sticks and cures pretty quickly. I liked it so much and it was so cheap that I decided to buy 3 more I epoxyed the tin signs to a brick wall with a very rough finish because they are difficult to screw or nail. They stick well and seem to be holding up pretty well. I'll update this review later so you know how well it's held up over time, but so far it's exceeded my expectations. So overall it works, it's pretty easy to work with, and it's great quality considering the very low price. I highly recommend it!
