These work very well. They protect our floor and when i move the chairs around the floor is not scratched. I like that the top part is clear so the chair leg is visible.
The uses are endless! Best of all, no rattle at 5:30 in the morning. There is nothing out there that addresses this issue.
These things stick on easy but dont stay on. The glue gets gooey and your left with the thing on the floor.
