Review on 🦷 Meyarn Teeth Whitening Kit - 28 Non-Sensitive White Strips for Tooth Whitening, 14 Sets Teeth Whitener by Matt Duffy

Last year I made, sawed and improved some whitening strips. But I drink more than 3 cups of coffee and/or tea a day, so it's time to do another set of strips. coffee and/or tea stains; I noticed that my teeth are 2-3 shades lighter than when I started. + They fit well so they don't slip off during the 30 minute exposure time. -- Too narrow/small! I am attaching a picture of these strips. (left) versus Crest 3D strips (right). These strips are too small, especially for people like me who have adult-sized front teeth; That means I can't cover the entire front of the tooth with it. Pity! I have to do a direct comparison to what I used last year which is Crest 3D White Strips and you can see the Crest marks are much larger making it easier to wrap the tip of the tooth covering the entire tooth covered, and also has no slipping. At least those strips on the bottom set are longer than the bottom crest strip, meaning you can cover your bottom teeth further around. BUT. in addition, the upper bar is shorter, which means that the main teeth (top front) that are visible when smiling are not completely covered by these bars. Since I don't have to suck and taste the medicine inside, it doesn't really bother me. But I know some people care about how it tastes. The taste is very similar to Crest. GENERAL INFO: IF they were made for ADULT teeth rather than CHILD teeth they would probably be 5 stars. Especially since they are much more affordable than the established brands that we find here in the US. But since they are too small = they have earned a rating.
