I went in a couple of weeks ago. and had great results. The office is nice and clean and neat, and very pleasant. Everything was easy, and worked just as promised. My teeth lightened by 10 shades, and the guarantee is for 8-15 shades of whitening. I'd definitely recommend this to anyone. Safe, effective, and minimal discomfort or irritation. Also, this was more affordable that other whitening offers. I'd go back again and get them even lighter, but I am unable to right now.
