Not worth it and hard to use
So hard to use and the gel just does not stay on my teeth, even with drying them completely. Tastes so bad and made my gums hurt from it getting on there. Whitening pens do not make it easier.

Didn't work for me
Brought this about 2 months ago been using and I don't feel that my teeth are anywhere near the white I want them to be...every since I chipped my front two teeth no amount of brushing flossing or using this pen is helping with the whitening of my teeth

Works Good
While this product works good at whitening, I had a somewhat hard time getting it to come out onto the brush after the first initial time I used it. I will use it again thought as it did whiten my teeth about 2 shades whiter.

Disappointing
Easy to use. Teeth not much whiter. Whitening strips much more effective.

Easier than the strips
I purchased this teeth whitening product after usually using the Colgate whitening strips. I was hoping for a more easy and efficient way to whiten my teeth. I found this pen to be easier to use and less painful. Also as someone who doesnt like the taste of the strips, this was easier to bear with. However, I think the effectiveness was less impressive than the classic strips. Also, although the instructions make it clear, it’s worth noting that you are meant to apply this product on DRY teeth. So i like to wipe my teeth off with a paper towel before applying this product. I think this might be why some people are complaining about the product being grainy or too difficult to apply— i suspect they aren’t applying the product properly on dry teeth. Overall, for an instant whitening effect that’ll give you an obvious and instant effect, i’d go with the strips. I think this is a good product for in between strip whitening or when you want a more subtle transformation.

Average
I have been using for about 2 weeks. I think it works about average compared to other products I have tried. . I will continue to use to see if I get better results.

Works great!
I'm loving this, it really works. I use it every night before bed & after the first week you can really see the difference.

Gritty feeling left on teeth was unbearable…
I’m had high hopes for this product but sadly I was disappointed. First, I will say I like the packaging but the product is hard to get it. It’s supposed to be left on overnight but the grit it left on my teeth was not bareable to sleep with all night. It didn’t have a smell or bad taste so that was also a plus. Do I think it did anything after an unpleasant week of slumber? No. It don’t think it worked that well to remove stains.
