Because many customers have this trio praised me I ordered it. I had a bit afraid before starting up, but that was unnecessary. It's all described in easy to understand the operating instructions and worked right away. I could even my old cordless phone (was also one of the Gigaset series, but an older model) insert in the group. I did not expect, but so much the better, because now I have a group of four. That I was able to play my telephone book was particularly pleased. However, this is only a device and not at all the same, but still saves a lot of programming effort. Also very nice is the Haustelfon mode. I can each part separately, or call all the same show, a super solution. The voice quality is good, clear and distinct. The eingauten batteries last very long and are quickly full. The menu is easy to understand and intuitive to operate. All in all, a very good house telephone, technically very good, looks very nice and the price is also moderate, what more could you want. Just buy it !!
