The Ergophone 307 has a Loewe AB replaced, who after 15 years left the service. The unique advantages of the new device is that no backup battery is needed during a power outage because the settings (text) can be permanently stored. Highlight is the extremely good speech quality (recording medium and speakers) and up to enormous level adjustable volume. Negative - and therefore only 4 stars - is that the calls do not have a time stamp, that is to be stored without time announcement of the call. It is very positive that all settings are ultra easy and the service is limited to the initial configuration at 3 keys. After habituation also is positive the rolling recording, ie after 20 records (each of max. 2 minutes), the oldest deleted (irrespective (!) Of whether or not already listened to). Some getting used to and criticized by contemporaries make is that the display always jumps back to zero after listening to the message (a roommate thinks then that zero, that there are no messages). Have the unit at Amazon needed, but bought "as good as new" to less than 2/3 of the price and do not regret the purchase.
