Negative Positive
Title: OK... One Star for pretty display!
Review: Except the pretty display, it is a poor quality item. It is very difficult to make a right contact with the Air Valve. I don't see how a o-ring will stay in place as recommended by certain users. It lacks a small metal stem to release air in case of over inflation. It is very annoying to look for some pin etc., while holding this expensive guage in your hand. Even the cheapest mechnical gauges have that stem. Last but not least... you need to hold the valve with one hand, while pushing this guage with the other. Now you got brake dust on your hand. Avoid it.
