Im ACTUALLY realy pleased with this!
I was hesitant to use a whitening product on my already sensitive teeth but this Brightlee kit is actually really good! A friend of mine recommended it to me and after the first few treatments I'm already seeing the results! I read another users review about the battery saver but that really wasn't very confusing. Its between the batteries to protect it during storage and shipping. My dentist charged me over $300 for teeth whitening and this provided the same results for a fraction of the price!
