This is a great product for whitening your teeth and really transforming your smile. It will takes years off your smile and this product is great for smokers or people that feel that their smiles are not white enough. This will give you lots of confidence in the whiteness of your smile.

Really whitened my teeth. I love that it stick to your teeth and stays. Can drink water even.

Love these little babies! They whiten so well. They don't burn your gums or make your teeth sensitive. Noticeably whiter in a couple of treatments. Have an event Friday start on Monday amazing white teeth!

I love these whitestrips. I've been using them once a year for 2 years now and I love the results.

They are easy to use and not messy at all. Some of the earlier white strips I found were very mess and hard to apply. These are like stickers that you just apply to your teeth.

They give a very noticeable difference too. Compared to other whitening treatments, this is very affordable, and you only need to do it once a year.

I've gotten so many complements on my teeth which is great! I will continue to repurchase these!

Loved this! I've always disliked the color of my teeth but couldn't afford whitening treatments at my dentist. Now I love my teeth! Best use of thirty minutes lol

The result is great, however after just using it once, my teeth became incredibly sensitive to absolutely everything. SO conclusion is that I would not buy them again.. And buy Aquafina trays!

Easy to use & nice outcome as teeth are getting whiter & taste is ok

Crest 3D White Professional Effects Whitestrips definitely works. I have always taken really good care of my teeth so they are pretty white before using this product but I wanted them whiter. After trying this I noticed a big difference after the 4th day. The only problem I had with this product was it made my teeth very sensitive which it said it would with some people. I found a solution to the sensitivity by using Colgate sensitive Pro relief an hour before applying the strips. It totally made a difference and I could use them without discomfort. I really like this product and will continue to purchase. It's cheaper then going to the dentist and it works! I would recommend this product

I used the 5 minute/day version of these strips which I purchased from Walmart. I was definitely impressed by the results! I saw results in a couple of days. These were way easier and tolerable to use as compared to the 30 min/day strips. The only downsides to this product that I noticed were that 1. the strips move around in your mouth and 2. you can taste the whitening gel in your mouth. I'm going to give the advanced seal strips a try and see how those turn out. I recommend this product to those who find that the 30 min/day strips are annoying and gross to wear but want the same results!

I have used these for a week now and this is my review. Brought at Walmart for around 30$.

The Professional Effects version comes with 14 strips (each w/a top & bottom) and the product claims you will see the difference in 3 days. In 2 days, I started to note a difference in my teeth colour - my smile is whiter than before.I drink coffee, coke, red wine, eat berries which all these foods/drink generally stain my teeth. I noticed the 3D strips are longer than the premium versions - which i love for the extra coverage. With the advance seal technology, you dont have to worry about the strips slipping or sliding off your teeth.

I recommend you put the strips on when your teeth are DRY and do not brush beforehand. Put each strip on for 30 min top and bottom. Be careful to minimize gum contact and sensitivity will be greatly reduced.
