Great product, as described, would buy again.
Not cheap but, after 6 weeks of use, are faring well installed in chair legs on a hard limestone floor. They don't seem to mark the floor and there's now no unbearable squeaking when chairs are slid back.
These pads are easy to fit and so much better than the self stick ones that fall off after a few weeks. Highly recommended.
I am very happy with how this went: information supply, ordering process, delivery. The quality of the inserts is very good. I recommend Keay Vital Parts.
Excellent product for our dining room chairs.
Speedy delivery as well
