Works quickly and efficiently
I got this because I am getting married in a few months and needed to whiten my teeth inexpensively.  So far after only a few weeks use I can see a noticeable difference.  I am very excited and plan to order another to get me through until the wedding.  My teeth are easily 2 shades lighter.  The system is easy to use and tastes great.  I have had no issues so far.  I will revise review if needed at the end!  So far its amazing and so much cheaper than professional whitening.
