LUCKIN SMILE 10pcs Teeth Whitening Gel Refill with 35% Carbamide Peroxide Suitable for Sensitive Teeth Whitening, Teeth Whiteners Used in Conjunction with Teeth Whitening Kits

Works great. Very satisfied.

awesome

I replaced my smile brand gel with this brand. I bought the same concentration as the original brand. This brand foams and makes my teeth sensitive while whitening them. Not sure if Ill buy again.

This stuff really foams up in minutes inside the mouth guard, which is great because it completely covers your teeth and gets into all the hard places. The price is great, the taste is fine and the ability to have it cover all your teeth is a bonus. I've had no sensitivity but that is usually based on the individual. Whitening is happening so overall a great product that I would buy again.

Whitens teeth quickly

I use this with my light. It works great. You definitely get a lot for your money.

They work great, good price.

Caused Serious chemical burns to my mouth, especially where it pooled under my tongue. Very painful; still healing days later. Used as directed for 3 days, after third day had pain and swelling. Bought this brand to refill gel for my Vie Beauti kit and regret changing brands.
