It is so easy to install and has an exceptional range of distance to the receiver.

Fantastic range, very sensitive and a great selection of tones.

The range is good, but not great, that's why I'm dinging it a star.

So far the range has been fantastic for his use.

The range and spectrum makes the device very sensitive to any motion

The range is pretty good.

There are a million options for the tone (OK, really only 30) and the volume can be as loud or soft as you want.
