This stuff is amazing!
This is the first whitener that I have ever used that showed immediate results!  I haven't whitened my teeth in a couple of years, and it was long overdue.  This took off two years of yellowing in two minutes.  I'm assuming it may take a couple of rounds to get them this white if you smoke and drink coffee, but my husband that does both will be testing it next and I will post the results then.  Wonderful and safe product!!  Will definitely be purchasing more!
