1. For the price you could every month raise a new brush head
2. Anyone who has ever tried a paddle which to clean without being wet?
3. From for Antibacterial. Since rubber with pimples everybody knows has not any material of view, the whole paddle hangs full of shit.
4. The shit is not brushed off, but is merely smeared rushed past to enough water or just all depends on the rubber.
I advise absolutely depend on this "miracle" to buy.
Unless one is on it.
