This is it! They are super affordable and they work! I use them once a week or so and I can definitely see he change in my teeth shade! Definitely a recommend for ne

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 have saved so much money with this at home strips they really do whiten. I would only use them as recommended and would not leave them on for any longer than that because they will cause sensitivity like any whitening product.

I have been using forever. They really do make a difference and you can see the difference in your teeth after one use. they are a little pricey, but they work wonders and are totally worth your coin! 

I absolutely love these. They 100% work, I don’t experience any sensitivity while using them. I just wish they were longer as they don’t go over all of the teeth.

A once and a while buy for me because of the price, but a great purchase for rapid results. After using them for a while, my teeth got super sensitive to hot/cold, so that is a downside.

Crest Whitestrips are the best over the counter whitening agents available, hands down. I don’t know why there are so many different variations (professional, luxe, etc.), they all seem to work the same, just with different price tags.

I’ve used this product for a long time, I really like it but it doesn’t keep my teeth white after a couple of days. Compared to other products, these have been the best over the counter white strips.

Didn’t have noticeable results the first two times. Felt like these strips irritated my gums and teeth too much for it to be a product I’d continue using.

I LOVE these strips only thing that I wasn’t aware of until after unfortunately is that is breaks down the enamel on your teeth if you are using it on a daily basis. So I had to start using it maybe twice a week and still got the same results.
