Unstable, unreliable. Find the best alarm clock.

They drain the battery fast and get unstable (false alarms) when the battery gets low so I reconnected the transformer to 9V which was a big improvement but still loud and nasty false alarms gave. I replaced the first motion detector with this one and that seemed to fix the problem for a while but after 4 or 5 months the same thing happens again. I gave them up and it's a shame. That would be a good answer to the double robbery of my workshop.
