Extra Strength Teeth Whitening Kit; 12 Syringes of 44% Dentist Quality Tooth Whitener Gel and 2 Thermoforming Mouth Trays

The gel is amazing and worth the cost. However, the UV light that comes with the set didn't turn off after the first use which required me to remove the batteries every time I used it which caused more issues with both the light and batteries. I do want to mention the mouth guard because I read it was uncomfortable. I did not have that problem at all but I did take care when molding them and cutting the handle off because of the previous comments, had I not seen those I may not have taken extra care.

I have used Opalescence 35% for quite some time. It seemed like my whitening had stalled, so I thought I would try this Extra Strength Teeth Whitening kit. After just one application, my teeth have whitened by at least one shade! The gel is easy to use, and you get A LOT.My only criticism is that it doesn't taste good. I accidentally got some on my tongue and it was an unpleasant experience. If it had a mint taste, it would be perfect!Well worth the price and well worth trying.

The gel is fine but the trays aren't much good. I'd recommend the gel to anyone who wants whiter teeth.

This products works very well. I could see a difference even after one use. I will more of these!! A++++

Waste of money!

didn't Work.

I got the 60 pounds argos one first and what a waist of money that was. This is strong stuff just dont get it on your gums like me it will hurt lol.y Teath are at least 4 shades whiter

I like how fast the shoes came and they were exactly as advertised and my feet are completely HAPPY!!
