We had a $3,000 theft on our property last October.
Ordered one of Miltronics competitors that was a bitter disappointment.
When it was working, it required fresh batteries every three weeks or a endless series of false alarms prior to worn out batteries in four weeks.
(I used DURACELL AA expiration date 2026 initial voltage 1.619V).
Sent the unit back to them FIVE TIMES, customer service is great, but repairs/ replacement unit were as bad or worse than the original unit.
Placing my hope on Miltronics for a quality unit MADE IN USA that will provide reliable service.
Ordered Home & Yard Alert EXT LR system so I am notified which area the thief are entering property so I can be ready.
