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

WOW!!!!! Works soo well! You'll be shocked!!! I am a tough customer and I give it a 100%! My teeth look whiter than they ever have...but not that glow in dark, non-human white some people have. It's wonderful!!!!!

This product works extremely well. Probably the only thing that I didn't care for is it had a taste of bleach. But I still would buy it cuz it did a great job.

I love this product. I saw results after a week of using it. I recommend this product and it also doesn’t feel harsh on the teeth and gum.

This totally works since the first time use. I love it

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.

This is my third time order. The brand is great. Has written my teeth up a lot. Still getting there as they were really bad. The taste is great

Great buy!!

Bad taste and made my gum and mouth burning and damaged. Not recommended at all.
