Excellent product. Used it 5 days in a row. I started seeing results day 1! By day 5 my teeth were hella white! I recommend this product to anyone who wants white teeth again. I’ll be using this from now on a few times a month to keep that Colgate smile shining!

Quick shipping, product is worth the cost.

The customer service department is very responsive to qiestions

Everything is great. Noticed a difference after 4 or 5 cycles.

No problems, quick shipping
