Years ago I bought crest professional whitestrips 30 min a day with advance seal,( not the 3D) It done exactly what it said, I got so many compliments and for a very long time, but when I tried to purchase again, It only sold in 3D professional with advance seal and it was nothing like the original and since I have bought another 3D professional this time with flex fit and it is very stiff (like it's old) and barely sticks with little to no results and yes I peeled off the plastic seal, pretty much done and not satisfied at all.

Love this at home teeth whitening strips. They are easy to put on and the results are awesome. You do have to do them often in order to keep them looking white but the product is good and it does work. It is more on the expensive side but if you want your teeth to look white, it will be worth it!

These are the only teeth whitening strips I use. They're the best ones I've tried. They really do get your teeth whiter. I only use them on the top because my bottom teeth are fairly sensitive and they start to hurt after using any whitening strip. Recommend for quick teeth whitening!

I absolutely love my Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit I use this when needed. You can tell the difference with one time used. I've been using this for years and and very effective. Please a reminder don't let it sit too long because your teeth can get too sensitive. I leave it on for about 20mins.

I dont think that this did an absolutely amazing job but it did whiten my teeth one or two shades brighter. I am a regular coffee and tea drinker so i worry about yellow and staining, this does a decent enough job of whitening my teeth. I use about every 6-8 weeks!

The BEST teeth whitening kit!! I saw results within 3 days of using, my teeth were instantly whiter! It's a little bit on the expensive side, but very worth it considering the results. I purchase this product all the time! I would recommend this product to anyone!

I have used 2 boxes of the Professional Result Strips bu Crest and I am impressed. My teeth wet from c-1 shade to A-1 shade according to my dentist. I am using them now as maintenance to keep my teeth as white as I can get. I just turned65 yrs old and have never smoked, but I do like tea and coffee, so I do need the strips to keep them as white as can be. Im about to buy my 3rd box.

I've only ever used Crest brand whitening strips. I feel like they always give me the results i'm looking for, and QUICK! I'm not a big fan on the taste/residue these strips leave, but i'm assuming it's similar to other brands. I've also noticed that if you use this product multiple days in a row it can lead to sensitive/ sore teeth.

This product works great. I bought it a few weeks ago right before going to a photoshoot and I am so happy that I did. It is very effective. I used it once a day for thirty minutes for seven days and there was a drastic change. I would highly recommend this to others.

I have tried everything, but it has been awhile since I have gotten my teeth cleaned, due to health reasons and "time just flies by" at this stage of the game. I am on my 4th strip, and with each time, I kept on seeing more and more whitening. Very pleased at this point. Hoping to get to where I want them to be...fingers crossed
