Works some
These strips are really easy to use and they did work, it just wasn't the results I was expecting. It comes with a tooth color chart as seen in the pictures and these strips made my teeth whiter by about 2 pictures. My mouth is small so they were somewhat hard to get on my teeth. They did not bother my teeth while they were on them but my teeth were more sensitive than usual after I removed the strips. Overall, I'm not disappointed in the strips.
