works without problems - recommendable product for a reasonable price

The bell is working as it should with no problems and no frills.
In the yard long, since multilingual product documentation, however, you will be held clues to use only safety regulations and information on battery replacement.
Apart from the removal of the protective paper with the existing battery in the transmitter and inserting itself be provided 3 AA batteries for the receiver, however, is nothing to do.

The transmitter can be fastened with screws or adhesive strips where desired, the receiver also attach either - or - so we do it - take each point where it temporarily, but it remains a long time and the "normal" bell does not stop, for example, garden / etc Keller
The gong I find loud enough and need no personal volume control for my purposes.

All in all I am very satisfied with the purchase and would recommend the product highly.
