They do what they are meant to do- protect the porcelain floor. They stick well, just make sure to give it a minute after putting them on before moving to around.

The backing comes off easily, the adhesive seems to work great, and the felt padding is thick enough to prevent any scratching. They adhere well. They stick well.

Heavy furniture glides smoothly. The chairs now slide with a silky smoothness. The cushions keep doors from slamming loudly.

The adhesion did not last, leaving carcass of furniture pads all over my floors. They are incredibly thin and flimsy. Expected pads as thick as the photos. They seem very thin, compar to the once we purchased with a different supplier.
