Very handy for on the go whitening!
This is very easy to use, the instructions well-written, and the packaging exceptional. I use this every 2-3 days to maintain a whiter smile. I was surprised that I did not need the enclosed desensitizing gel. I'd like the mouthpiece to be just a bit softer. It hits on one side (bottom), but I have figured out to tip up the mouthpiece and it no longer is uncomfortable.
