It has a huge selection of melodies and it is certainly something for everyone.
Saving a new tune you have made my opinion very awkward. So what could be much easier to solve (-halben Star).
The volume can be controlled very well and the maximum volume can be heard throughout the house.
To reach I can only say that we are throughout the house have no problems. I have not tried it yet, the extent to which 300 meters are realistic. , But I hope that I can take the bell with the garden in the summer.
And now the reason why I pull 2 stars.
In my set the bell was no longer on the outlet after about 1 month.
As I have already broken my old, I divided the bell (am a trained electronics technician).
A resistance was broken and that's why the bell was broken.
If you can not repair itself, man 2 weeks, no bell again and that's annoying.
The bell works with my parents still (about 2 month).
All in all a relatively good bell at a low price, but you have seem to have luck.
