There has bever been a better product out there!!!

I received a trial offer of Crest's 3D whitening toothpaste, mouth wash, and whitening strips, and honestly, my first thought was: sure, nice packaging/advertising on the products themselves, but will they actually work? I am a heavy coffee drinker (at least 7 cups a day). The difference before I brushed and after (first time using it) was astounding! I couldn't believe my eyes!! You can actually see the whitening stuff go to work! Then I tried the teeth whitening strips and that is where I really was amazed....It took months of stains off my teeth in one use!!!!

Cheaper than dentist but same results

I love the comfort and effectiveness of these strips. They are some of my favorite ones and don't leave a nasty taste or sensitivity. I highly recommend them if you want a quick but professional whitening solution at home for much less than the dentist charges for whitening.

We can assure you that our products go through many quality checks to ensure they reach you in the best possible condition, and we apologize for any confusion. We'd like to mention that this product is intended to arrive in a cardboard box, as it's suppose to ship in its own container. For best results, we suggest you use your Professional Effects strips first. Use 1 every day, or as close to every day as you can, until the entire set of Professional Effects strips is complete. Professional Effects strips should be worn for 45 minutes. After you have finished using your Professional Effects kit, you can use 1 Supreme Bright Boost strip each month thereafter, to maintain your white smile. Supreme Bright boost strips are worn for 1 hour. As well, the box should contain 27 sachets in total. We hope this is helpful, and your comments will be shared with our team.

Not Accurate

The strips came in a plain box with no instructions. Not only that, but there were no super bright strips only regular. Not as advertised.

Buy in-store

Wish I would have read the reviews. They came in a plain box with no instructions. Something very fishy about this.
