Arrived sooner than expected, plug in unit wall mounting in any orientation, well wired and good quality components, although galvanic isolators are easy to wire in, its good to know if there is a problem, with the warning leds, this helps, also there is an led test cable which makes checking the leds easy too.

Peace of mind that my boat is not dissolving. Just plugs in between the landline and the boat.
