text: Horrible I went to the Scottsdale location It was in the back of a store The room was dirty The guy was unprofessional You sit in a red outside lounge chair the guy applies the gel then the light Then the guy trys to sell you toothpaste and other products During my visit he proceeded to make telephone calls to other people including his friends and supplier Lastly the result was just ok I paid for applications but he only put some on my bottom teeth then some one my top teeth I could have got the same results at home Do not waste your money
