Review on Accu Gage Bicycle Gauge Presta Valve by Omar Thorndike

I had no problem fitting a pressure gauge to the valve stem with no leaks but when I removed it from the valve the pressure went out before I I could read it without touching the exhaust valve. I read something hoping it would get better, but it didn't. Revain took it back as defective. I removed a star because the description doesn't say it doesn't hold the pressure until manually deflated. So it's possible that this is a design flaw that they are aware of. Every pressure gauge of this design that I have had in the past has always held pressure until the relief valve has vented. You need to change the rating or the product. However, if you don't mind bending or crouching when the gauge is on the valve, then this is a functional gauge at a decent price. Hence the 4 stars.
