Good
I like the product a lot because it was for sale with a good price, it is a bit confusing because the box says 10 min use and then the instructions say 30min.. I used the light for 10 min and therefore did not get the full whitening experience I expected.. wish that could be fixed so we could know it is 30 use not the 10. Over all, it is still a good product
