I do enjoy using this teeth whitening strip. It really does help whiten your teeth a bit. It is a process. You have to be pretty consistent. I say to use the stripes at least 1-2 times a week especially if you have super sensitive teeth. You can also get the one that's good for sensitive as well.

I can honestly say the only downside to this product is that it does leave your teeth sensitive but that shouldn't be a difference between any other whitening product they're very easy to put on and it's good like I'll put them on before I get a shower and then take them out when you get out and you don't even like really realize you have them on Waze her teeth white impression

I recently started using whitening products. I heard from a friend that and she highly recommended it. I see noticeable results just after one use. I try to use them twice a week because I have sensitivity. So that's my only downfall but that might just be me. Try it!

Ive been using Crest Whitestrips for years (Advanced Seal) and always noticed a huge difference. I received soo many compliments and people were always asking me what my secret was. I recently used the entire box of Professional Effects (Luxe) and honestly so no changes. Not sure if there was any change in the formula but i am a bit disappointed. I still think its a great product however and should definitely be given a shot

I'm in college so you know I drink a ton of coffee, which means my teeth are constantly at risk of being stained. However, I use this product religiously, especially in the summer. They work so well and you can see immediate results, as well as long lasting! Definitely recommend!!

These really work!! I started using them in high school and continue to use them today! They do make my teeth a little sensitive the next day. They're easy to put on and don't have a bad taste to them. Got my whole family hooked on these babies! Love them

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 used crest white strips in the past and loved them. They always work and do the same job as getting your teeth whitened at the dentist, but for way less money. My issue is how small the bottom strip is. It’s oddly small... I am not sure if I got a faulty box, but the strip only covers up to each bottom canine. So weird!!

I always have a box of these handy! I really enjoy how simple it is to use this product. No need to hold a light up to your mouth or use messy charcoal powders. This product is two sticker like adhesive that you place over your teeth and leave on for about 30 minutes. I only give it 4 stars because it makes my teeth sensitive for the day.

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.
