Review title is Waste of time: simply does not clean your teeth [SEP] It is important that you clean your teeth properly and this sure ain't gonna help in any meaningful way.<br /><br />The so-called "wireless" charging consists of a base you plug into a USB adapter (not supplied) which has 4 metal contacts on the top. To charge the device you stand it so that two contacts on the underside of the base make contact with two on the base. It's pretty basic and falls over quite easily.<br /><br />Once charging is started a pretty (pointless) blue and white light pulses gently for several hours.<br />After charging is complete you can use this to clean your teeth, by putting the "brush" in your mouth and turning it on. The only problem is that it doesn't do a good job. Various presses of the one button make a blue light come on and the whole device vibrate gently. This is totally insufficient to clean your teeth.<br /><br />I persevered with this for several days and my teeth felt horrible, like I hadn't brushed then at all.<br /><br />In summary - worthless.
