After several weeks of use, positive feedback. Does its job very well. Two negative points: No possibility of external power supply and for battery replacement, it is necessary to use a screwdriver.

Works very well. Quiet and no signal loss. Alone, the power supply does not meet the "9Vdc" standards: grounding isolation required!
