These are great-looking and soft. with a nice pile height. We haven't installed them yet, but it seems that the three tape strips should be enough (although I'd prefer an all-self-stick backing). But the edges aren't bound well; corners are sloppy and some long edges are bound inconsistently, with loose binding. The worst thing, though, was the packaging! Vendor shipped these treads in boxes, unwrapped, with no outer packaging. The boxes arrived damaged with the treads exposed. Fortunately, only one or two seemed to sustained damage, but I've never seen a worse job of packaging. Thanks to Wayfair for hearing my complaint and making an adjustment.
