Better than most...for the price, at least
They worked fine, only issue is had was that the plastic tabs didn't take much pressure and they bent out a little. I guess that's better than cracking/breaking off, however.

20 pieces in the box, in grey. That works out at $0.25 a piece.
Stated material: plastic, metal, glass.
Our pack of 20 grey mirror holder clips includes screws and wall anchors for immediate installation. The 21 mm length fits standard 1/4-inch glass with a 6 mm offset. High impact plastic resists cracking while rust resistant metal hardware secures the mount.

Every figure above belongs to this line. Where the maker states no figure, the row stays out instead of carrying an average.
This line comes as 20 pieces, which is how the range prices it and how it repays comparison. The per-piece figure above is the price divided by the count, rounded up to the cent, so it never sits lower than what you pay.

Used these to install my mirror to the wall in my home gym
Thick and sturdy! Much more durable than the ones I've seen in big box stores. Great value for the set.
The only place I’ve seen these used is in mounting a light-weight mirror to the back of a door. I don’t know why mirrors don’t come with these anymore. That’s what I used it for, and it worked great with a power drill and the right bits. Took maybe 15 minutes.
Doing great holding up a very large mirror!
