Seems a good product (I have to see if it'll last without rusting though). Only bothering problem is that the holes are not centered with the 220 v plastic socket behind .. so you have to enlarge them with a tool.
Solid workmanship - but the screw holes do not quite match the associated shore connection box! I had to widen the four screw holes on the Niri cover a little upwards. Only then was it possible to function correctly. The shore connection is now visually appealing.
