I'll start by saying these strips really do work. The only down fall is that they make your teeth extremely sensitive to ANYTHING. Even air lol You can see results in the first use. And the price point isn't too bad. If you can handle having super sensitive teeth for a day then this is perfect.

Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit Love these whitening strips! Be sure to set your timer because once they're on, it's easy to forget about them. I once left the house and went grocery shopping and forgot I had them on! The strips stretch and you can cover your back teeth as well. You also get two bonus one hour express strips. I've seen such a huge difference! Highly recommend!

Honestly, I don't think I noticed a huge difference. Toothpaste can do what these strips do. They taste a little funky, and don't stick to my small teeth very well. They're expensive for the small impact. Just spend the money and get your teeth professionally whitened if you want to see a difference.

My sister is a dentist and recommended I use this for at home whitening, and I have been very pleased. I am a coffee drinker by morning, and red wine drinker by night, so definitely needed something for my teeth as I age. These have been great and I have gained a few shades brighter.

I like the fact the strips stay in place and you can go about your normal business. I've even taken them to a girls day to share. I do wish they were wider to fully cover the back of the teeth as well. This is my preferred brand and have purchased them several times.

I used these whitestrips and I was very surprised to see that you are able to see a change right away. At first they can feel very uncomfortable but then you get used to them. I do believe that they are expensive for you to repurchase over and over again. Overall, I was satisfied because you were able to see the difference in your teeth. 

I LOVE this product! The first time I used it, I didn't notice a major difference; however, as I continued to use it I noticed my teeth got significantly whiter! I used the treatment several times in preparation for a photo session, and I was so happy with the results. If I leave it on for too long, my teeth can feel sensitive after use, but it's never for long and the payoff is worth it!

I use these all the time for when I have an event that I know I will be photographed at. They cause no sensitivity in my teeth and they work really well, especially considering the cost compared to the cost of a professional whitening treatment. Highly recommend!

The hype for this product is crazy so I was excited to try it out but found them to be disappointing. I didn't notice much of a change in my teeth color and found that the strips don't extend far enough back to get some of my teeth on the back/sides. They did leave my gums/teeth a bit sensitive after use but the sensation did fade away after a few hours. I would not buy these again :/

I thought i didn't have Sensitive teeth but when I did this for a little bit my teeth start to get insensitive and then I started doing it once a month and it still hurt my teeth so just be careful make sure you don't hurt your teeth but they made my teeth really white
