Press On Nail Tabs

HORRIBLE! I go above and beyond when I apply false nails. I lightly file my nails as well as the back of the artificial nails, clean with alcohol before applying, and firmly press each nail for at least 5 seconds to stick. Within ONE hour a lot of the nails started lifting and coming off! Didn't get them wet or use my hands at all before this started happening. I tried three separate times and had the same results. I was hoping these would be a good replacement for the Elegant Touch tabs I've been successfully using for years, before Ulta stopped carrying them. Sally Beauty has some that work well, but they're a little thick. Please don't waste your money...
