Remote receiver works up to 1000 feet away (less with obstructions), 4 volume levels, led indicator, 52 chimes/tones, magnetic sensor uses 1 AA battery. About $21 from Amazon!
The only thing that could be improved on is the tiny groves to hold the battery door on could be a little stronger. I put a tiny piece of clear tape on each end for reinforcement.
