Listen I’m no poet I’m a 55 year old 36 year hard hat wearing Union Carpenter from New York. I’ve been smoking since I was 10 and drinking coffee since I was a teenager. Tried other products on the market and burned my gums and teeth bad. After using Snow there was no gum or teeth sensitivity and a noticeable difference after one use. And the second key factor was 75 Applications for a little over $100. If I saw a difference in one use I can’t wait to see my teeth in a month. There’s nothing more to say the product speaks for itself I give it an A+ 100% Zach from Snow you’re the man!
