It will probably sit in the garage unused for the next 5 years.
Very interesting to see some feedback on that particular one, as I'd been looking for one a while back and that was one of the ones I'd looked at but come to no real decision on at the time. To get an actual user of the gauge saying it does the job helps a lot!.
