You know what's the biggest problem with g-tech? finding a place were you can use it without being pulled over by a cop (probably called by "concerned citezens" seeing you doing circles in an empty parking lot).
Brief product review:
1) value per $ - excellent
2) mounting - bad, the tripod with the suction cups needs to be much bigger to provide stable mounting. You can think of making a custom-designed mounting bracket, (preferably not at the windshield level, i.e. invisible from outside, but it's not trivial since it has to be visible from various directions if you want both lateral and longitudinal data)
3) ability to measure g forces in cornering? - it's not as easy as the manual says. The car tilts to the side while doing a circle, and one needs to average readings with 180 degree flipped device. And how to read it? I tried mounting it on the opposite windows, but than comes the correction for the different radius depending on the location of the device.
3b) Similar problems are expected when accelerating or breaking in straight line, as the car doesn't stay levelled!
4) a good device should have two sensors mounted internally at the opposite angles to average the readings.
5) In my opinion, the only way to make this g-tech usefull is to take it appart to separate the sensor from the display, so that you can read data for variuos orientations of the device without moving its actual location. I'll probably do it when I'm done with sorting problems with my 944, but who knows when that will happen.

Mine arrived on Saturday in the mail. 5 working days total since I ordered it. Thanks for the tip!
Now, I just have to wait for the snow to clear and the salt to get rained off the roads to test it. This should be fun. Watch, I'll have done all this work to the car to only have results that are the same or worse than stock as quoted by the factory..
..LOL!
