I've been looking for a phone for my mother and I been able to find the Gigaset E310 and E310H. The difficulty lay in finding the mother in law is paralyzed on one side and also no longer has your good eyesight. I have several other manufacturers looked at the Amazon offered and have to admit that I am also one of the more not necessarily looking at the brand. The reason why I bought the Gigaset is that you can store more numbers to the speed dial keys than other manufacturers. Installing the phones is very simple and described in the manual. It also has only one device (base unit), for example, enter the Telefofonnummern and this can then send it to the second or third handset. Furthermore, the operation is very simple and the keys have the right size. What was of course is beneficial, but what I have not considered that the old phone was also a Gigaset. The settings for the volume levels for listening, speaking and the ringtones are as you would expect with such a device. In addition, the telephone 15 is cheaper than in a specialized market. Thanks for the many other reviews that have allowed me the right buying decision.
