We are very pleased with our Gigaset duo. The sound is very good and we quickly forget how it was with the analogue telephone. Very good reception when the phone is in the exterior garage a few meters from the house. And what happiness more searching for phone jack to connect the duo, a simple electric socket is. Explanations of commissioning are very understandable, the longest was to enter all phone numbers. Luckily the number has been transferred from one handset to another. Thank you Amazon delivery to been respected.
