First set of stair treads has dye that was very mismatched, ranging from pale gray (lighter than product images) to very dark gray - nothing actually matched the "teal" color I ordered.  Customer service sent a replacement quickly, which was great - except exact same problem again.  I now have 26 total stair treads and STILL don't have 13 consistent enough in color to use.  I'm asking for a refund now, I don't have any interest in taking a chance on these for a third time.  Save yourself the time and hassle and order something else.
