I've used CWS Professional Effects several times. I was on vacation with my sisters and they asked how I got my teeth so white? I told them Crest White Strips - Professional Effects. As soon as they returned home, they bought a box and now they have beautiful white teeth also.

Lets face it, we all want a perfect white smile but in wanting so work needs to go into it. I grew up with crooked teeth and they werent the whitest I wanted them to be so what happened I had braces for 6 years and after they were taken off I had to start phase two:whitening. I religiously brushed and rinse 3x a day only using 3D white products and added the professional whitening strips to my regimen. After a few days the results were mind blowing! I had that perfect white smile I had wanted, a 180 difference since I was 13.The packaging is different but the results are amazing!

Whoo boy. This hurts my teeth from the second I put it on to at least five days after I take it off. Slimy, slides off of teeth, bottom not big enough to cover front and back, and the taste is real bad. I couldn't try this long enough to see results as I care about the health of my teeth

These are my go-to whitening strips. I do them about once a year, and constantly get compliments on how white my teeth are. In the past, my teeth were quite yellow naturally. My only complaint is that I get extreme sensitivity when I use these, but that is normal and I usually combat it with a sensitive formula toothpaste

I have sensitive teeth and was so surprised but these didn't make my teeth hurt. I do definitely notice a difference is my shade. I am an avid coffee drinker and these are saving my teeth. I use them every week or two depending but they're super convenient and easy to use

Absolutely does what it says it does. Whitened my teeth dramatically after getting my braces off. It did make my teeth sensitive for a while even after finishing using them, but that is most likely user error. I kept them on for double the time I was supposed to usually. They stick on great and dont slide around so you can actually talk without getting a foamy, slimy spit mouth. Definitely a little pricey but totally worth it every once in a while in my opinion!!

These strips are AMAZING! They stick to your teeth and do not fall off when you talk, like other brands. It only takes thirty minutes and I could tell the difference in just the first use! The first time that I bought them, I used them every other day for about two weeks. My teeth have stayed very white. I drink coffee everyday, so naturally they will get a surface stain from that, but with one use of these white strips, my teeth are perfectly white again! I would recommend these to anyone looking for a great whitening product. They are a bit pricey, but definitely worth every penny!

Good at home whitening kit for those needing a quick “lift”. This is not the best product out there , but it's over the counter , easy to find , no mess and pretty affordable. The main drawback is that it sometimes leaves white dots on the teeth. In order to prevent that , I kinda move the strips around on my teeth before allowing them to settle for treatment.

For an at home whitening product this is one of the best. I try to whiten once or twice a year and this is my go to. I see real results every time I use these. The only thing is my teeth become very sensitive after use but after using tooth paste with sensitivity components it helps and goes away. Worth it and would definitely buy again.

Tastes horrible and saw minimal effects. It was something I dreaded, sort of tastes like a bleach mixture. Like actual bleach taste. If I used this consistently for a long time it might get my teeth where I want them but it's not a hassle I think is worth it.
