Great product & even greater value!
This is the best whitening option outside of a dentist’s office) that I’ve tried yet (& I’ve tried everything from toothpastes, whitening strips, even the gel that you put into mouth guard-molds that conform to your teeth).  Detailed instructions for optimal results, ease of using/applying the whitening solution, & actual/visible results are much better than 2 other products I’ve used that were virtually the same (design, advertising claims, primary ingredient). I highly recommend.
