Not suitable as an emergency cell phone for seniors

The mobile phone is well made, and the functions are easy einstelbar.Als children mobile determined ok.
But when an emergency cell phone for seniors who are no longer the best ear is unsuitable, the phone is in one meter distance in handsfree mode much too quiet, even I could understand hardly over. Here I now a real emergency situation, determined in the bustle and confusion prevails certainly can neither family members nor emergency services dispatchers to communicate to me with the victim.
Even the micro has a poor amplification, the participant does not speak directly into the microphone, come the words badly over.
Have it sent back to the test, and will now test the Doro mobile phone.
Unfortunately, provide the tailoring of immernur full phones facing many seniors are afraid. Please developed more 4 or 5 keys phones.
