20-Day Ultra Vibrant Whitening Strips - up&up™

I had moderate whitening results. However, with a small mouth, the bottom strips were too large. I couldn't open wide enough to apply them properly, so ended up cutting them a bit on each side. Then, the ends of the bottom strip came loose two or three times during the 30-minute sessions.

I've been buying crust white strips for years and those have always worked well. With everything getting more expensive, I tried this up and up generic version. I see absolutely no difference. I'm halfway through the box. Waste of money at least for me.

My daughter has been using these and her teeth were noticeably wider. I decided I would go and get a box for myself. For me they work great. No issue with them being too stiff. Actually when I take them off the strip, they curl up a bit so I try to make sure the strip doesn’t roll up on itself. No issues at all with slipping but I do wipe my teeth dry before applying. Removal has been no issue either. Overall very satisfied.

These left white patches on my teeth. I do have calcification marks that do get way whiter when using strips, but these spots are not calcification marks. I tried two times and the only thing getting whiter is the odd splotches they are leaving. 1000% do not recommend. I see comments saying they don’t stay on or are hard to get off but i had no issue. No sensitivity or anything. Just the splotches.

This was my second time purchasing these! I see results very quickly when using these. Coming from a dental assistant though make sure you aren’t using them too often or your teeth will become sensitive!

These strips are the best. I’ve always had fairly white teeth and a nice smile, I have larger teeth and I am always being complimented on my smile. These past three months have been the most difficult months of my life and sadly, I took upon smoking cigarettes. In 30 years, I never smoked a cigarette until now. My teeth quickly became yellow. I became embarrassed of my smile, that was once my best feature. I purchased these strips last month, and told myself once I quit smoking I will use them. Tonight I decided enough was enough. Ditched the cigarettes and threw on a pair of these whitening strips. WOW! One use and my pearly white teeth are back! I did keep them on a little longer than the recommended 30 minutes, and the residue stuck to my teeth after removing them, but I was able to wash it off. I was shocked how well these strips worked. I feel so much better having my white smile back. Also, I have very sensitive teeth, these strips did not irritate my gums or teeth, which I have experienced in the past with other brands. Totally recommend these strips. Btw, I never leave reviews! But I’m so pleased with the results, thought I’d share my feedback.

Not flexible enough to use on bottom teeth.

I have used these before. They used to be a pretty much spot on dupe for the Crest version. However, these have changed. Now, the adhesive hardly is effective. As soon as they are applied, they are slipping and sliding off. Do yourself a favor, spend the extra $12 and buy the name brand version.

These work well, definitely take a bit longer than the Colgate ones but I really like them

These strips are too cheap and do not stay on your teeth! Next time I will buy name brand.

Ironically sticks to my teeth a little too Good. I had to use my fingernail to remove some of the left over product. I noticed some sensitivity. I used Colgate total and in a day the sensitivity was gone. Overall for the price it whitens well and does the job. You might want some sensitivity toothpaste on hand in case you need it.

Love it. Worked great

These were impossible to remove and caused strong sensitivity that lasted for days. I also didn't see much whitening results.

[This review was collected as part of a promotion.] I really liked these actually. Super easy to use. Just follow the directions on the box. I noticed a difference after using them for a week. People wpuld tell me my teeth look really white. My kids thought I was brushing my teeth more than twice a day. The packaging is nice and easy to open too.

Truthfully, they work better than crest in my opinion! They also don’t make your teeth as sensitive!

I made the mistake of deciding not to buy the Crest ones. These don’t stick well and burns your gums. Don’t recommend.

Good price , works well & not too harsh. Did not cause me any tooth sensitivity. They do slip so cutting them in half helped keep them on better.

MY ABSOLUTE Favorite! I buy these over and over again! Just as great as other expensive brands!

I have issues with this product adhereing to my teeth, especially the lowers. Within 5-10 minutes, the lower is starting to fall off, and never makes it the suggested 30 minutes. I do as suggested, and don't brush first (been 9-12 hours since last brush, usually). And the taste causes my mouth to water, which makes it even harder to keep on the lower teeth.

Provides same results as similar products at a lower price point. Only complaint would be that the strips sometimes get stuck to the inside of the wrapper, so use caution when taking out the strips!
