there’s definitely some whitening effect but i wouldn’t say 8 shades lighter. i use it everyday for 2 weeks without skipping and cut down on my tea intake(not much of a coffee drinker and i don’t smoke) did not cause me any sensitivity probably because i have been using toothpaste for sensitive teeth prior to this which helps a lot.

I can’t get these in the uk and have heard great things. I can’t believe how amazing these are after only one week of use. You do get some sensitivity, as with all whitening products, but if you use alongside sensodyne rapid relief it relieves it very quickly

The best among all whitenings. You need to brush then dry your teeth before you use it. Then leave it for one hour not 30 min and then after you remove it brush your teeth with the a wet brush and rinse your mouth. Better to use everyday. You will feel pain in your teeth at the beginning and red gum, it is normal this will go away a few days after.

I think the pictures will speak for themselves, but I'll still add a few words. 1. it works. 2. you can see a big difference in your teeth color, even after the first use. (to be honest, you see the biggest difference after the first few stripes, and after that I didn't notice much of a change, but only a mild one.) 3. very easy to use, I followed the explaination and didn't had any problems. 4. I think I have sensitive gums and teeth, and it says you might feel discomfort while using - I hardly felt it. only twice, and again, it was mild. 5. I think the quality and value for price is good. I'm attaching a before and after pictures of my teeth. overall - highly recommended.

i bought it as a gift for my friend however i saw a difference on her teeth. affter she used it. as they got whiter and cleaner. it has good benefit and the price is good. she really liked it and would recommend as it is great quality. also it has simple packaging.

great quality product. it really works as intended. Will definitely get more soon! Thank you so much for this. it was made of high qualiy ingredients. Plus the packaging and sizes were perfect. over all good quality. i love the smell and the looks of it. im looking forward to purchasing another one!

Finally gave these whitening strips a shot as I'm a huge coffee/ tea drinker and my teeth were getting a bit too yellow. After only 3 sessions (with 3 day gaps in between), my teeth are looking a lot whiter. Plus my sensitive teeth are not aggravated by these strips. I also use a whitening toothpaste about once a week for maintenance.

Crest Whitestrips are my all time favorite from all teeth whitening products. I have somewhat sensitive teeth so I use them every other evening before sleep. They really stick properly, after 30min I remove the strips, rinse mouth with water and go to sleep. Great results. The package is ridiculously big but oh well I guess they want to be noticed :) Overall really recommend, great product.

I saw real results after using this product 3 times (3 strips). Good to use if you have an occasion soon. There is no flavor just use it on clean teeth. The product is gentle and easy to use the strips are not sharp and don't hurt the gum.

I tried a lot of whitening products in last couple of years and nothing gave big results, at least not long term. When I heard about these strips, I was a bit sceptical at first, but decided to give it a chance. And I am so glad I did! My teeth are so white, I don't remember ever seeing them this white! I used the whole pack, 14 days straight and each day I could see my teeth getting whiter. I did feel mild sensitivity first couple of days, but it was worth it. Also, worth mentioning, I am a heavy smoker and I enjoy a few cups of black coffee each day. And my teeth were really, really yellow. I will definitely keep using these stips twice a year to keep my teeth this white always! Highly recommended!
