We purchased this rug pad almost a month ago and it has performed as it should...the rug hasn't slipped out of place and no one has tripped over an upturned corner.

There's absolutely nothing wrong with the pad but we are looking for the felt fabric type rug pad as we have hardwood floors and were forewarned by friends that rugs/rug pads can leave permanent etch marks in the wood flooring.  This hasn't happened to us but as it did cost our friends a large amount to eventually refinish their floors, we'll learn from their mistake.

If we had anything other than wood floors we would be perfectly happy with this rug pad.

I gave it a four star rating because it does work fine but I am worried about any damages from long time use.
