This is an actual rolling counter meter so there is no problem reading it from different angles or in direct sunlight. It works just as it is desgned to do. I am of the opinion that this is a very good choice when selecting an hourmeter.

This Hour Meter was easy enuff to mount on my 172N panel to replace a broken one of a different make. Hopefully it lasts forever. Its relatively cheap considering its a panel mounted gizmo. It would seem most things that screw into a panel are well over a 100 dollar minimum.
