The device is also easy to handle without reading the manual. The On button is also the off switch you have him just minutes. Hold for 2 seconds. The brush rotates in 2-stage principle at different speeds. The model provides design an integrated suspension-ring, so that no further charging station / battery lying around in the bathroom.
Unfortunately, the batteries that were supplied, have held only 1 day for an application. They were either old or of a low cost producer.
According to the manual, the brush head to achieve optimum cleaning results every 4 months to be replaced. This is where follow-up costs, similar to an electric toothbrush. A new change brush costs a quarter of the total purchase price. So that everyone can decide for themselves whether and how often they would like to change this brush. I personally feel that you have with the changing of replacement brushes to high costs.
Furthermore, the instructions say that you should make sure that no water gets into the device. While this is in principle understandable for a product that is suitable waterproof with the statement and for bath and shower, I find the information quite questionable.
You have to test yourself how much water can withstand the unit ??
