Good monitor, poor quality screws for fixing it. Monitor looks fine and load alarm, but 'don't spoil the ship for a ha'p'orth of tar'. This monitor is sold for caravan and boat use but the screw fixtures provided with it are not corrosion resistant.

Seems OK to me. I find the "test" mode/procedure a bit confusing even as an engineer - and I have read the intructions twice! Also the green light is so dim you can barely make out which adds to the confusion.
