I have used TWO Jaycos (didn't want to spend money on an ARB) and both were junk! Luckily I bought both from Revain and they were returned with no problems. I took a chance on buying this device and was very skeptical that it would be any better (since I suspect almost all of these things are made in the same factories in China). That's about the same price as a Jayco unit (when it's on sale, which it often is). I'm glad I took the risk! I have used Buddy's ARB device many times and this threads smoothly, pulls out the stem and deflates the tires very easily (as well as the ARB device). psi is high at 30psi) but it's stable so I'm used to stuffing my tires to 34 when I need 32. If I'm unlucky enough to get a good one, it's a really good buy and I recommend it. The gauge doesn't have a liquid-filled dial, but I don't think that really matters unless you're in a high-vibration situation and need something to steady the pointer. (not necessary to air the tires)
