    "I worked in dentistry for years and this is a very strong and effective bleach gel. I really like how white my teeth turned using it. It must be maintained on a regular basis and works like a professional product."

    "I’ve tried several at-home whitening products over the years, but this Teeth Whitening Gel for Trays with 44% carbamide peroxide is hands-down the most effective and easiest to use. I’m honestly impressed with how quickly I saw real results!"

    "Finally teeth whitening product that actually works. This doesn’t take a lot of the gel to make the teeth actually start getting wider after just a little bit of time. This is an amazing product and a super great value for that price."

    "This whitening system really works. It's much better than the Crest Whitestrips. I used two boxes of Whitestrips and barely noticed any difference. So I ordered this set of peroxide gel. It's easy to use and the gel is as strong as the gel I got from the dentist 20 years ago"

    "I’ve tried a few whitening products over the years, and this one actually works. The gel is strong but didn’t make my teeth super sensitive, which I really appreciate. I used the trays that came with it (after softening them in hot water to fit my teeth), and after just a few sessions I noticed my smile looked a lot brighter."
