Review (1/5): Waste of money, it doesn't clean anything.
So this product idea is really good but not practical when you use it. First, it doesn't have enough power, so it will not clean anything, it will just be high-speed water. The design is also not that convenient while using the water will spill across everywhere as you move it around your tooths. Overall the product is not of that great if you are serious about cleaning.
