Yeah, I seen this on a commercial one day and knew then and there - I had to have it!!
I bought it from the supermarket for like $29.99 and apparently it was on special then, but you know I was like well if it whitens my teeth then I really dont mind, show me the results!
Its quite exciting to use, if I'm honest. I got a few of my other family members keen to give it a go (I must be the cool kid of the family haha). So you brush your teeth like normal and then detach the whitening pen and kind of just smudge it along your teeth. It doesn't really taste that good and dont get me wrong, it did whiten my teeth - but not as I would have thought. I dont know, maybe my expectations were too high but i think the media really made it out to be waay better than it ended up being.
I didnt buy it again once the pen run out. I bought a $10-$15 teeth whitening toothpaste and to be honest, I am a lot happier with my results now than I was with the whitening pen.
All things aside, it did make brushing your teeth a fun event :)
This product did not meet my expectations. it didnt whiten my teeth at all if anything made my teeth feel dirty and not clean at all :(
