The delivery took place (as usual) very quickly, ordered Wednesday, Friday came the postman with the packet. I still have the previous model Panasonic KX-TG8421 and wanted me not for 95, - (!!!) buy the corresponding handset KX-TGA840EXB, for me the price was just too high. In a review now someone who also has the previous model and has appointed the successor model KX-TGA850EXB that the registration of the handset worked without any problems with the older model wrote. I can only confirm the part was found immediately, the phonebook entries you could copy the same completely by means of the copy function. The KX-TGA850EXB can also be loaded on the base station from the KX-TG8421, works without any problems. And for less than a third of the price of the 840 handset you need the decision no longer to weigh, so full 5 points. Quality, whether processing or comprehensibility of votes are awarded. Previously had a Gigaset ... something, because the handset was after a power failure no longer found, no chance ... Since I have the Panasonic include such problems of the past. Very strong buy recommendation ...
