I've only ever used this whitening kit and it works really well. I can see a difference after one use. They re a little expensive, but i feel like all the whitening kits are

We have been users of whitening strips for many years. We tried the 3D Whitestrips this week. What we found was that there was hardly any whitening product on the strips. We will go back to our old product.

i am very self conscious about my teeth. however this product helps me fight that! i put them on while i drive to work or do my makeup and that's so easy !

I thing that the Professional effects whitestrips are one of the best products out there. All the Whitestrips are somewhat sensitive to your teeth, but after a while you get used to it. Start out by using them only once a day---or every other day.

I love this brand and buy it for my relatives like a gifts. Very visible results after first applying. Highly recommend, but if you have sensitive gums, consult your gentist before using it or at least make using time shorter.

These are great if you are willing to consistently use them. I have sensitive teeth and these did not irritate them at all. It took about 4 days from me to really notice a difference but if you are consistent it's worth it!

Love these. Whiten my teeth tremendously and do not take long to stay in. Only downside is results are more visible after a couple times. But i think they work good.

I did notice a difference in my teeth after using this product. The strips itself I think have a weird taste to them but it's worth it for the results !

these work so well! they left my teeth looking snow white. they are extremely effective and definitely the product to use if you are looking for quick whitening!

It was alright, I felt like for the price I didn't get the level of whitening I'd expect, and I felt like I'd had better results in the past with the crest white strips that had the squishier product.
