I really like the tread carpets. A nice color and feels good under foot. There is a tiny difference  in a few carpet treads as far as the width. A couple of the treads have edges that are just a tad not perfectly straight. But for the price, they are perfect!  The non-slip backing feels very secure on my wooden stair steps. I will not need to use tape as I feared I would.  I would recommend these carpet treads to anyone that wants to cover up scratched wood steps. I would buy again.
