This is really good stuff. After one use
This is really good stuff.  After one use, there was an immediate improvement.  It wasn't CRAZY or SUPER white but it felt amazing and my teeth were whiter, especially my K9s (or as my wife says, my fangs). It does make a HUGE mess so hold your breath when you bring the toothbrush up to your mouth.  I also recommend placing a paper towel or kleenex under the container to help prevent a mess. I use it about once a week and I should probably use it more.  I drink a lot of dark things (coffee, soda, and so on) and more regular use would have a big impact.  For a few days after I got it I was using it once a day and the results were really dramatic.  You'll love this but you have to be careful of the mess.  It won't stain anything but it can be a huge pain to clean up.
