Query: Not Worth Buying - deserves a zero star rating.

AceHardwareOutlet is excellent with shipping and service, however this product isn't so excellent. The first unit failed after one day. Ace immediately sent a replacement. The second unit worked for a week and began behaving erratically. It either doesn't turn on, or won't turn off, but then it also turns itself on. I have fresh batteries, no other electronics that would interfere and followed all the directions. Cannot recommend.
