Great idea, poor construction
on May 27, 2010
This device works great... when it works at all. I bought one last year and my deer problems vanished. I loved it so much I bought one for my in-laws. Then the problems started. The one I bought for my in-laws didn't work at all. Since I was an electronics tech, I was able to diagnose the problem: The power switch was broken. I purchased an identical, replacement switch and popped it in. The sensor + ultrasound started working correctly but the water pump did not turn on. It turns out the pump was bad as well. Meanwhile, our unit stopped working. I took it apart and found that the sensor/electronics unit was totally filled with water from our winter rains. The circuit board was completely corroded. The unit has inadequate seals and will not withstand a single winter. I'm not talking snow and sub-zero temperatures here. I'm talking about ordinary, California rain. It's a shame that such a great device could not be built and QCed better.
