The 44% peroxide is very very effective, it does take a week or so to allow your gums to get adjusted to the chemicals if you haven’t bleached your teeth in a while. The chemical burns were no laughing matter for the first 2-4 times using. I dropped down to the % below 44% and use it twice a week after using 44% for two weeks straight. Incredibly impressed with the results. Read more
I drink coffee all day, and my teeth weren't whitening with other products. I tried 1 TIME and it worked, it's that good. So I bought more for family members. I think that says enough of how great it is Read more

One thing I didn't like about this product is the battery charging process, too long. Read more
No support, light fails quickly, very poor quality. Bought the kit with high hopes, it worked for 4 times then the light was dead. Not the battery, it hums for a few seconds then nothing, replaced the battery and had the exact same results. Contacted the manufacturer and they said that particular unit is not supported. So I have 4 tubes of their jel but no light to activate them. AVOID this product and company. Read more
