Very pleased with the results!
I really do not care for whitening strips and have tried several whitening pens over the years...but this one is by far the BEST!  I followed the instructions exactly and only used for 7 days.  I began noticing a difference by day 3!  It is easy to use, the taste is refreshing, and it's not messy.  The whole process was super convenient and worked wonderfully for me!!
