I wish I'd read the reviews! I've used many jumper strips over the years. It has the worst adhesion ever! Yes, the surface was dry and I tried a hair dryer. Nothing. So now I have these ruined strips that I've been trying to - hopefully - place around the tub. I want to return and you want me to send these cut pieces back? Read reviews for your defective product, folks! It doesn't stick. Looks like I lost a few bucks. Do not buy!
