Query: Oh WoW!

You guys can flame me if you want. I bought this two years ago and left it in the cabinet this whole entire time. Through out the entire time I was just using my electric toothbrush. I guess I find it more faster you know. Brush teeth, head straight to tongue after, and rinse. Well guess what? My toothbrush died after three years. Then I was using a manual brush so I thought hmm I'll give Dr. Tung tongue scraper a try. OH boy, I was blown how amazing this thing cleaned! Much much better than my toothbrush. The only thing different between this and my toothbrush is the after taste. Dr. Tung left metal taste which one last for few minutes and my brush left a toothpaste taste. Anyways, this product rocks.
