I had high hopes for this Longacre gauge and filler and have owned several Longacre products over the years The Longacre 52-52009 tire gauge doesn't come cheap and I'm generally willing to pay more for good quality gauges, especially those used to measure pressure, current, RPM, etc. Unfortunately, Longacre shines with their gauges replaced with very cheap hoses and fittings and having greatly improved the product cheaper I have not yet measured the performance of the gauge compared to the professionally calibrated gauge I have but will update that estimate when I do.It is too expensive for the apparent lack of The fittings are very light and unlikely to last long.
