4 Medium Rectangle Rectangular R... vs NON-SLIP 16 PREMIUM Furniture Pa...

These are built fine & sturdy. Also a metal * built in for the screw to snug up to is a plus.

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.
