Honestly, stay away! Have let myself be fooled by design and good reviews. We have a lot of Philips sonic toothbrush, etc. Areas Everything really top devices. But this device loses after less than 30 m receiving. We are currently on holiday and the connection breaks off in the restaurant, which is located about 25 m from the bedroom. Problem we had in our house on 1 floor already, but we have by issuing our phone (I think) a little better to get a grip. Dear grab here with an alternative product! We will definitely get another device.
