Product really works… wife noticed duff after only few days… I use 2 or 3 times a day…no unpleasant taste

I like these whitening gels because they can get in the nooks and crannies. They have a good viscosity so they don’t drip everywhere. My favorite thing is the precision brush tip and ratcheting syringe so there is no wastage or overflow. It’s the best applicator I’ve used so far. Super easy to use. The packaging and insert have clear instructions (refrigeration recommended), but there is no mention of what the ingredients are or the concentration. While the gel bubbles like other peroxide whiteners I’ve used before, it does not seem quite as strong as the gel I normally use which was 35% peroxide (purely based on oral sensation and level of tooth sensitivity). It’s hard to precisely quantify the level of whitening, but it does seem to be working. I would guess somewhere on the order of half a shade every three or four treatments. Mild to sensitivity does seem to go away after several days. No notable gum irritation. Good value at $18. Overall, pretty happy, but I wish there was a listed peroxide concentration. 4/5 stars.

I bought this product to try it...Very disappointed..for $15.00 .this poduct does not do anything .It's false advertising .They should refund my money Iam appalled that Amazon would allow any company to sell an inferior product to AmazonPrime customers ,that does not work...very very disappointed

So far no sensitivity. Easy to apply, you just need to make sure you aren't planning on eating or drinking for 30 minutes after applying and that you have a way to rinse after 30 minutes. I've just swigged and swished from a water bottle on my morning commute and sit out my window...super classy. LOL.Does work...not crazy results, but definitely does something.
