I've been using Crest white strips for several years now and have been extremely satisfied and happy with their results. It's not the results I'm disappointed in, but the fit of the latest version that I purchased which have a terrible fit for your bottom teeth! In the past, Crest made the bottom strip smaller/shorter & it fit great, but now it's the same length as the top strip which makes it difficult to place on your bottom teeth. It also doesn't stay in place toward the back on both sides and now that you need to leave them on for a full hour (rather than 30min. twice a day), it's not comfortable....my husband is in agreement! I hope Crest will consider going back to the other smaller strips for the bottom teeth in the future!

i do these strip kits every so often and i always get compliments! the effects are noticeable!! they work like charm. i wouldn't recommend using everyday because too much could be damaging to your enamel. when used in moderation, i think these are great and a great pamper investment.

Crest 3DWhite Luxe Professional Effects Whitestrips are an easy and affordable option for teeth whitening. My teeth are pretty white already, but I use these to keep them that way. They are easy to use and give a great result in a little Mount of time.

I used the strips on my teeth and they were super white. Everyone that I encountered on campus said that my smile was gorgeous with my white teeth. I have only used this product twice within a seven-month span and my teeth are still white. So I would recommend everyone to use it! :)

This product has done wonders for my enamel shade. I am not a smoker and do not have reason for staining. My teeth are just not as white as I would like them to be. I was not expecting miracles, but I did improve a few shade to make my self confidence sky rocket :)

This product stays on until I remove it after 30 minutes. Everywhere I go people say WOW, you have such white teeth and such a beautiful smile. People ask me what do I do and I tell them its 3D Whitestrips and I Love them. Thank you for a great product

These work very well. They are super easy to use and quick as well! Some people have sensitivity when using these whitenening strips, but I did not. The only time I had sensitivity is when I did two treatments in one day (and it hurt), so I recommend sticking to one treatment each day. Pretty expensive but worth it.

I saw a Huge difference in the color of my teeth. These shirts in my teeth so so white. They did however make them feel a bit sensitive but this has been a problem with any sort of whitening strips I've used. They did not damage my name although according to my dentist and I would use them again just have to space out when I use them

I love the old Crest Whitening Strips, but these new ones are terrible. They don't hold, I have to keep checking and making sure the strips are on my teeth. I didn't have to do that with the old ones. You guys are losing quality fast! I'd say save your money for a whitening treatment. ESPECIALLY if they're going to keep producing these low quality strips.

These are my go to. They make your teeth visibly whiter after one use. They don't taste very good but I use them before special events for 45 min - an hour (the allocated time is 10-20 min) and my teeth are GLOWING. I use them very sparingly as they make your teeth sensitive but I absolutely love these and can't imagine not having them
