Saw these in a news feed and was very curious but not entirely sold on them until a friend said she got them for her husband and she loved them (no more messy floors) and he liked them (didnt have to take boots off every time he came in the house), so I ordered a pair for my husband.  They work on both his cowboy boots and his round tie work boots.  Were both happy with the purchase and timely shipping.  Company actually inquired if I was satisfied with them and that says a lot that they are there even after the sale.  I definitely would do business with them again.
