I returned my broken one, I couldnt fix the lights, not sure what the issue is wires had good connections. but store took it back and they had plenty available, make sure to test them before buying.
Count me lucky. Mine arrived a couple of days ago. The packaging was rough and the blister was almost separated from the cardboard once the padded shipping envelope was opened. Fortunately the PKE meter looks fine and has been working normally so far.
