I've used these whitening strips a few times. They're fast acting and work pretty well. They left my teeth a shade white after using every day for 2 weeks. I only wish it worked faster and wasn't so pricey.

I love using these! I had braces when I was in middle school and my teeth were not cute when I got them taken off. I bought some of these and I still use them today because they are such a good product.

You can NEVER go wrong with using these. However, I find that every time after using a white strip, my teeth become extremely sensitive for a couple hours so I tend to not use these often.

May I know why there’s an uneven whitening after my first use of 3D professional effects white stripes? Should I continue or stop using the remaining white stripes? Hope to get your reply soon.

It does improve the whiteness to your teeth but it won't happen quick this one takes a while for it to build up and it also gives you a weird sticky feeling attach to your teeth and the taste is awful

The strips were uncomfortable at first but you get used to them and they are not so bad. Gave me an even white smile in the matter of 2 weeks but did lead to increased sensitivity.

Love these so much! I have issues with teeth sensitivity when using whitening products and haven't noticed much with these. I definitely notice a difference in whiteness when I use these! Highly recommend!

I LOVE THESE STRIPS!! I use them before any special events for a few days leading up and they make my teeth noticeably whiter! I have had many compliments and questions about how I got my teeth to be so white. They are 100% worth the price!

This product plus the toothpaste has helped get rid of the tough braces stains I had growing up. If you're looking for easy whitening that doesn't take long and is effective I would recommend this product.

I feel like they work the best out of other comparable white strips. I use them every few months and notice they definitely work well except along the gum line !
