Delivery was quick, now two weeks into use

but the device does not work, no matter what settings. At the slightest movement (the dislodgement, lift etc.) switches the device off and all the settings are gone. This is quite annoying. Alarm in the beep sound is not heard've repeatedly slept, even with two alarm settings at the same time nothing works. My iPod can load not always, so as a charging station unsuitable. Have it sent back today and am going to order another device and not only look at the price.
