Just as described and met my needs. They are perfect.

I can’t say it’s easy to use because that would be dishonest. You have to get a cleat firmly attached to the wall and level. Managed to get this one on the wall correctly and it’s holding up a very large mirror without any complaints.

Used 2 on a plaster and lath wall to hang a solid wood headboard (we use two twin bead frames instead of a single king). Our wall was at a minimum a quarter inch off of flat, and our old house doesn't have wall studs a standard distance apart, so it took a little finesse to get both (a) as many fasteners into studs as possible and (b) enough washers installed behind the cleat to make sure it was flat enough that it would mount the actually flat (or mostly flat) headboard. None of these are faults of the cleat itself, but are common enough problems that it's something to take into consideration. I think more options for places to put the fasteners would be possible, without compromising the structural integrity of the cleats, which would make it 5 stars.

Used this to hang an unique wood artwork that was 65 pounds. This set up made it easy. I didn’t trust their molies but used larger ones due to the weight

I bought these to hang four crates under my tv in my bedroom. They are very sturdy and esy to hang with or without studs.
