For the price, these are great!
Easy to install, feels safer than bare-wood.

Did not receive five stars for three reasons:

1.  Manufacturing inconsistencies.  Some treads were not rectilinear.
2.  Threading/finishing.  Loose threads around the perimeter, should be stitched up, and not cut as the jute is exposed.
3.  Glue on finished surface.  It looks like the carpet tape glue threads ended up on the carpeted surface of some of the stair treads.
