Really nice! My dad installed on top of a new particle board underlayment which we sealed with polyurethane prior to laying these down. He also used a 3M spray adhesive to just make sure it would really stick. As others said, there are definitely going to be peices that don’t quite line up (pictured) but most of it was perfect. If possible, buy the amount you need at one time so that they come from the same lot, otherwise you may have a harder time with tiles not lining up with each other. I bought at 2 separate times about a week apart.
