Ecco Pure Teeth Whitening Kit - 2-Pack Gel Pens Included - 35% Carbamide Peroxide - A Pearl Smile White as Snow

These pens are amazing! They are easy to use & I could see a difference in one day (3 uses). I have found the best way to use this is after brushing my teeth, applying it on my front teeth, & then making the worst face to keep my lips off of my teeth for about 10 minutes. The taste is very very unpleasant, but the results are well worth it.Above is a picture UNEDITED. TRUE results. The first photo is just normal whitening toothpaste twice a day, my normal routine. The second picture is one day into using these pens. I use it 3x a day, the first being after my morning coffee, the second after lunch, then right before bed. The last picture is 4 days in, 12 total uses at 3x per day still. Results are amazing!

I really have a neutral opinion about this product. Yes, it whitens, but it doesn't stay on your teeth. You just eat it. The only way I can get it to do what it's supposed to do is by covering my teeth with the trays I have from another whitening kit. That's the only way to keep the gel on your teeth long enough for it to whiten anything. I'm not sure how other people are getting this to stay on their teeth without going around for 30 minutes with a strange grimace on their face so their mouth stays open nonstop...

In the past I have used a certain brand of whitening strips that were very expensive and made my teeth sensitive. This price is excellent and I can see results within the same day and the next day and it made me want to smile more often.. However I don't know if it's a miracle product because I think I have seen brighter White with a different brand however this is very good and I probably would buy again just for the price alone..

This product is amazing! I saw results immediately and everyone is asking what I have been using. I drink a lot of coffee and now I have dazzling white teeth.

Product not as good as reviews. I read many positive reviews and decided to buy it. However, I now realize I cannot fully trust those reviews. I don't have a good experience like others. Product made my mouse feel very bad.

So easy to apply directly to full tooth! Works fast! I am using with the charcoal brushing also. Only my 2nd day and teeth are already whiter! Love this!!!

Easy to apply to teeth on areas needed.Did not remove simple coffee stains on my old teeth as well as plain hydrogen peroxide does, or the "crest whitening strips".Would not recommend this product for stain removal.

No real results. Product doesn’t stay on teeth long enough to work. Followed instructions completely several times.
