Review on 🦷 Cool Teeth Whitening Zero Peroxide Strips for Sensitive Teeth and Gums - Whitener Band Kit (28 Pcs, 14 Treatments) - 2 Week Supply with Color Chart - Gentle, No HP Bleach Free, Instant White Tooth - Non Slip Formula by Angie Anderson

I was skeptical about them as they are peroxide free and much cheaper than the competition. I've been using them for a few weeks and I can see a noticeable difference in the whiteness of my smile. I drink a lot of coffee, red wine and Diet Coke, but I like sparkling white teeth. They definitely do the job and don't cause tooth sensitivity. The only thing I agree with is that the bottom strip is difficult to hold and the strips leave a thick layer on the teeth. However, the rest is easy to fix; I only bleach in the morning and brush my teeth right after. I will buy again.
