Bests & Worsts Reviews from Amazon

I originally took a before image and planned on comparing. However I also realized I didn’t have adequate lighting for the before image so it didn’t work out so well. When I received this item, I thought for sure I received a broken, unusable product. I read that some other consumers had had some issues with nothing coming out of the tubes. It took about 5 minutes but I finally got mine to work: The first few times I applied this product I was unsure of the best method. I soon learned that applying it to the top first and allowing 30 seconds before doing the bottom worked best. Drying my teeth and surrounding guns before both applications. I’ve been using this product for a week and a half and am happy with the results. Though my teeth weren’t very dark to begin with, my teeth are noticeably whiter. I did not experience any sensitivity while using this product though my teeth are typically very* sensitive. I chose to not use it twice a day but only once for this reason and still received the results I was hoping for.
