I've only used this set once, mostly due to the high price. While it does whiten your teeth pretty well for being something you can get at the store, it did make my gums hurt/burn when the strips were on. This discomfort is not awful, but it seems like there are other ways to whiten teeth. For the price it does it's job, but be warned about the burning.

This is extremely effective in whitening my teeth. I have been using the Crest White Strips for many years now and I am very satisfied in the end results. They do an excellent job of brightening and whitening my teeth and removing stains. I would say the one drawback is the sensitivity of my teeth afterwards and a couple of days following after using this.

I used to love these whitestrips when they were in the purple box with the Luxe line. They were my go-to and I always noticed a difference within a couple of days after I wore them. These new packaged ones are garbage and do absolutely nothing. So disappointed.

I use these 4 x a year for maintance to keep my coffee stains at bay.  I don't experience any sensitivity or pain from them.  I don't like the sticky mess they leave on my teeth but its tolerable.  I don't like stained teeth and this gives me some control over the situation.

Like many of the other reviews stated, mine came in a plain brown cardboard box with NO INSTRUCTIONS. I've used Crest Whitestrips before and the individual packaging of the strips looks legit. After checking the Crest website, they show the same brown box container so I'm gonna try them and see.

Just bought this recently and the results are amazing!! I have many years of coffee and soda staining on my teeth and these completely whitened my teeth. Everyone has also noticed the difference and though my teeth are pretty straight I was getting embarrassed to smile, but not anymore. These are life changing and the price is well worth it, though you will experience some sensitivity, just take caution when using or space out the days.

Your "no slip" whitestrips are extremely difficult to remove, so much so that the first time I used them, I was afraid I was going to pull the enamel off my teeth! Your earlier form of this product which were easier to remove from the backing, and much easier to apply and remove, with better whitening results. Please consider returning to the earlier form of this product. I will not buy this again.

Crest professional effects is so easy and it whitens incredibly !!! I always get compliments on my white teeth and when I tell people that it is from crest whitestrips they are shocked !!! It looks like I got them professional done !!! Awesome product !!! Worth every penny!!!

My teeth would be much more yellow if I didn't use this because I drink coffee daily as well as tea and wine. These can definitely make your teeth sensitive though so I use these only when I notice my teeth are trailing behind where I like them to be in terms of whiteness.

Even thought it is very bad for your teeth this product is my guilty pleasure. I use it about once a week if I need it. But I bought it a couple of times and was never disappointed. I definitely recommend it works very well and whitens after 2 or 3 times. Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit
