Insane quickness on whitening after leaving on for 30 min . After one use to be exact. No horrible taste. Just peel after and brush excess black from charcoal strip . But results are insane!!!! Better then crest !!!!!and price is affordable… I recommend

Pretty good considering you can buy it at the dollar tree. Not as good as the alternatives but more affordable. I recommend using them asap if u buy them because otherwise they are hard to peel off the wrapper

I’ve been using this whitener and I can see a little different on my teeth. Is not a surprise, my grandma introduced me to charcoal homemade toothpaste but the color of your teeth is what it is. It whitens for a while then it goes to my basic color. Too much whitening weakens the teeth because it looses the natural dental enamel.

Ive always struggled with tooth and gum sensitivity when using other strips. With these, I no longer have that. They do a pretty good job at whitening on the first application and have a good taste.
