These stair treads are just "OK".  Nothing special for the price!  The cut was not completely uniform - some of them were a tad wider or a tad longer, but once they are down it's not that noticeable,  The biggest issue was getting the protective layer off the adhesive tape on each tread.  There are 3 strips on each tread.  They seem to hold OK - but I just put them down.  Time will tell.  BUT...if the thought of spending a lot of time trying to peel the backing off the tape doesn't appeal to you...you may want to pass.  It probably took me a good 2 hours to successfully peel the backing off 12 treads.  On a couple of strips I just gave up completely.  I didn't want to spend $400 on the more expensive bullnose treads...but now I wish I did.
