You bet WG.
Yeah, it is just annoying after just 4 or 5 checks on a known tank level. Not fun. Not even close to precise. Hit-and-miss. Just frustrating.
I can see this thing in a year or 2 now - I'll find it in the garage with a dead battery.
I'm sprinting back to the good old hot water down the side of the tank with a quick feel and you always know the LP level method.
