I have been buying these for 3 yrs and I'm so disappointed with the 2 packages I bought this yr. I can't even tell that I'm using them. When I first started using them I tanned instantly. Then I continued to buy them ,but for some reason they are not working at all. I hope they aren't outdated because then I feel I got cheated. I will probably not buy them anymore. Don't want to waste my money...
