I had high hopes for this Longacre gauge and filler and have purchased several Longacre items for the shop over the years. The Longacre 52-52009 tire gauge doesn't come cheap and I'm generally willing to pay more for quality instruments, especially those used to measure pressure, amperage, RPM, etc. e. Unfortunately Longacre seems to have replaced the very cheap hoses and fittings for their gauges and made the product a lot cheaper. I have not yet measured a meter's performance with a professionally calibrated meter that I own, but will update this review when I do. It's overpriced for the apparent lack of quality. The fittings are very light and probably won't last long.
