Title: Junk with fatal design flaw
Review: It is extremely difficult to make a sealed, air tight connection between gauge and tire stem. What's worse is that when it beeps (to tell you that you have a good reading) if you don't immediately remove it, I mean a flash fast muscle twitch reaction, it resets itself and erases the reading it just took.Since I was wrestling with making the connection, my hands, the gauge and the air stem were in constant motion. I had no way to remove the gauge right at the precise beep moment.Since it costs 75 cents for 3 mins of air at most gas stations around here, I spent $1.50 just to top off the the inflation levels...and I wanted a hammer to beat the gauge into the asphalt.I've thrown it away.P.S. Some have mentioned O rings and the "new" version but I bought mine in October '08. It was anything but new and improved. Finding and installing an O ring for this gadget is way beyond my pay grade. If you think you can do it, it's probably a great little gizmo.
