The best and most accurate tire gauge I've ever owned period. The case is a bit cheap but the actual gauge is awesome. I had reservations about the clip connection but it works great and allows you to operate this gauge with 1 hand if necessary. I have 3 different gauges by Accutire and they are all equally accurate. This gauge has the advantage of reading in 0.1 PSI increments which is really precise. I've owned 2 other racing gauges from Blue Point (now owned by Snap On) and the Accutire blows them away hands down. Really impressive product.
I was about to order a replacement for my old accutire "Racing" air pressure gage until i read these reviews.
The gage is not as easy to use as a one piece gage and the hose adds several places for failure to occur, but it seems to be very accurate and repeatable, which is important to me as i drive a porsche on interstates where the speed limit is 80mph and the ambient air temperatures are well over 100F much of the year. I can feel slight differences in pressure so i appreciate the 0.1 psi increments and the porported close tolerance of the readings.
The valve stem retainer clip failed shortly after i purchased ths one i own (several years ago) and now the hose leaks at the gage end. Not worth trying to fix. I have thrown it away and will look for an accurate, easy to use replacement. BUmmer.
Another example of a good product idea poorly executed, and I can say that with some authority as i am a licensed professional engineer (TX, Retired) whose specialty is machine design. HTH.
I needed to change battery; screw tight and stripped. Now faced with drilling it out as I have no idea where to send it to be fixed. The leaking valve stem connector is annoying but overcome with a little "adjusting". As the last reviewer evidently tried to get service and lost his instrument, I suspect I'll make do with what I have until it finally fails.
