    I don't think that's the case. When I inflate a tire, I see a dramatic
    increase in pressure on the downstroke, then I usually hear/feel a
    click, and the pressure stabilizes. I'm assuming that is the presta
    valve opening to let the air in the tire. When the pressure is greater
    on the tire side, it closes. That air rush is just left over air in the
    pump.

    Now, I think schrader valves are a little different, because the
    inflator has a little pin that pushes the valve open. When you remove
    the inflator, there is a lag that can let some air out. This is really
    noticable with the screw-on inflators.

    still a gauge that doesn;t use the valve would be cool.

    What problem does that solve? Before every ride I check the tire
    pressure by letting out some air, and inflate it to the desired
    pressure. It is a routine, like putting on your cycling shoes and
    filling your water bottles.
    Checking the pressure with a gauge that doesn't use the stem, conclude
    that the pressure is not OK and then inflate the tire with a pump with a
    gauge sounds silly to me.
    If you want to get used to this routine try latex tubes ;-)

    it solves the problem of doing all that.

    if the pressure is ok, why go through all that?

    Through all that? It costs 30 seconds.
    Boy, you must be on a tied schedule.
    I think the thumb method will be as accurate as an external and indirect
    pressure gauge. And much cheaper.

    difference of opinion.

    that is why i want the gadget and you are happy
    with your routine.

    Maybe its just me, but my tires loose a bit of pressure everyday, so I
    always have to add some air with the pump anyway. I don't think the
    non-invasive pressure tester saves anything, and actually costs time. I
    attach the pump and add air, you non-invasively check the pressure,
    then attach the pump and add air--unless, of course, you are not
    concerned with having your tires properly inflated and are willing to
    ride with a pressure deficit that is within your tolerance, say
    10-15lbs psi.
