Regardless of what some of these reviews say, I have been ordering from this site for last 7 years and always been happy. Good luck finding better products and prices anywhere online. I get compliments for my smile thanks to the products I buy from them. I like the usalabs and pola 22%, I tried crest white strips but they were not evenly whitening my teeth and not as strong. Anyhow happy customer and love the loyalty promo codes they send to repeat customers
