Very good. They do what they say. I put them on soundproof panels on the wall and after 5 months so far (including summer, etc.) everything is great

It holds canvas frames of the stretcher type well. I placed medium-sized canvases in the room without damaging the wall with nails.

With 2 1000-piece puzzles on the wall, it looks really nice as if it's flying. And when you get bored of it, you can easily change it.

I used them to hang canvases on the wall and they are excellent for this job, but they are expensive because each package is only for two canvases. Prefer the medium or small size that do their job very well instead of paying for the large size

I was very satisfied with this specific product! It is easy to use and supports the frames I hung securely.

I used it for a puzzle that I stuck on cardboard. It sticks well both on the wall and on the cardboard.

So far I have only used them to hang canvases on my walls and they have been very helpful. Initially, there was no way I would sit down to hammer so many nails and of course I would do it clumsily and the frames would not have the proper spacing between them.
If you want to hang a frame on the wall or something heavy, I do not recommend it. But for many light things, it is ideal!
