The stuff on the strips is working but they are really inconvenient. The strips do not stick well and they are difficult/messy to put in place to begin with. I apply them carefully, let them sit about 10 of the 20 mins, then remove the strips (the gel stays on your teeth), and finally I use my tooth brush to move it all around my teeth for the last 10 mins
