Very sturdy. Replaced on all my dining chairs. Overall good, not great.
Be sure to drill a small hole with a diameter smaller than the nail first to avoid splitting the wood leg. I typically just add a round felt sticky pad to make the chairs quieter.
Box only contains 39. Thin gauge nails result in bending when hammered into chair legs. Also the nail has a tendency to break off from the plastic backing. Broken x-protector after trying to simply hammer it into the bottom of a chair leg.
These work so well that it is difficult for me to move the sofa when i want to. Keeps chairs from sliding and prevents floor damage. No more moving couch on the hardwood.
These pads turn into a sticky goo that is all but impossible to remove from the floor. There is not enough adhesive. Leaving sticky scuff marks on the floor.
Reviews suggest it may have been a bad batch. Reviewer is very disappointed.
