I purchased this product in addition to the Gigaset C300A Duo Pack with integrated answering machine. It is easy to implement. It is a nice design and a good grip. It is easy to configure and allows many configurations, such as call screening, especially copy contacts from the integrated directory from one handset to another. Easy identification combined with a proper name (bedroom, garage, lounge, etc.) and an easy to read screen. Quality of listening to the appointment, soft to the touch keyboard, no heating sensation in the ear during a rather long call. Anyway ... the Deutch Quality !!! (Many options). By cons, read the instructions (it is not used to calibrate the mobile during transport). How to customize your mobile and it sympathetically. Good use ...
