They feature the lamest single-layer board design possible and are pretty much naked and open to anything coming down the mains wires or the interconnect signalling wire. I have one where static electricity discharges on a carpet on the opposite side of a subfloor will trigger a beep if the wire runs too close to the subfloor. Someone must be hauling home a fortune in profits on those things - they are as cheaply made as possible. | |
