Rubberized grip pads keep hard drives from sliding. Adhesive is strong enough to hold up on most surfaces.

Anti skid/slip rubber sheet is excellent. Can be cut into any shape desired. Had a little harder time than anticipated cutting a nice circle using scissors.

Product is not as advertised. The pads are useless. They are now in my junk drawer gathering dust. The one pro is that it’s very easy to use and customize.

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.

At least the adhesive backing is worthless on smooth surfaces. Black felt from this outfit sheds a lot of tiny black fibers.
