These things are just overpriced for what they do.

This is an awesome company with a great product, and even greater tech support.

Fair price fast delivery.

does the job, Watchout for the sun.

Good product good company

have two of the same units --so I new it was A good product

Oh, it works great but after a while of the sheep passing by it one at a time it gets kind of old.

Works. Just had to follow the instructions, since this required programming the receiver with each specific sensor unit to enable its operation. As in past use, I also painted my own drab camo coloring on the sensor unit to make it “hide” in the front yard foliage by my driveway where I park the unit (photo). It’d be nice if they just came in that color already. That last one I had lasted almost a decade despite permanent exposure to sun and rain outdoors (along with getting kicked around occasionally by night animals).
