Used these before about 6 years ago. They worked so good and made me so confident in my smile! I started using them again like a week ago, and have yet to see results. I'm sure that once I'm done with the process, I'll notice a difference!

Love using this it does help out to whiten my teeth the only thing is it's very pricey for my opinion but the product it's self is great.Crest 3D White Whitestrips 1 Hour Express Teeth Whitening Kit

The stuff is really amazing it goes arm really well it stays on really well it works really great for my routine I like the packaging the product itself well put together I will buy again and highly recommend others

Although it's a process to put them on your teeth, it is so worth it. It has made my smile 10x whiter and my friends & family can notice. Although it's pricey, it is totally worth every penny! I would recommend trying these out!

I have used crest 3D whitening strips maybe twice within the last 4 years and my teeth are still very white! It stung my gums a little but at first but went away after a few minutes. I will buy them again when I feel the need to touch up!

You can see results just in one use! I have used these on the plane before vacations or before big events like weddings. Easy to use and to travel with.

For the price, this is a great product! I can definitely tell a difference when I use them. Easy to apply! I've bought several boxes over the years. My dentist even recommended them to me! I will continue to purchase!

Many of my patients use this product and express that they are very pleased. I notice their teeth are whiter and brighter - and as a result, they are more motivated to care for their smile to maintain that great look!

These are so easy to use and stay put from the moment you put them on to the moment you take them off. I would use these over and over again. I haven't used anything like it before. I'd definitely buy again.

I thought it would come in the packaging like in the photo, but it comes in a cardboard box with no instructions or anything. Just thought that was weird.
