Deduction can be found at the selectable tones. There may be 52 (I did not count!) But the melodies are simply for a door / -klingel too long (playing time) and therefore not purposeful.
This is subjective, but who has desire to listen to up to 10 seconds each time a bell melody?
For a "bell" too long. However, if it is, who can access courageously. We chose the standard - decided Ding-Dong, because it is one of the shortest tones.
In short good to very good.
