The device serves its purpose, is easy to grow and also the arrival and Ausschalttechnik with the band works for two months yet (with some older models I have since heard of difficulties). Visually, the device has also improved over its predecessors. Only the cable is very short, as you mind the unit. 1 meter is to install on the changing table and one mostly in height has no outlet, it is necessary to extend definitely the cable. Price Leistumgsverhältnis is definitely true in this device.
