Tried it tonight on the hhr ss and it showed 14.65@97mph which is right where it should be. I actually like it better than the gtech because it is wireless and compact.
Here is where I got it, a fun little toy to have and they are pretty darn accurate, i have used these accelerometers at the track several times and they are within 1/10th of second typically.
You better grab one before they sell out.

I can take a vid tomorrow if anyone wants to see it being used.


MrPhotoman, Thanks for the info. Just ordered mine, and I think this is the same meter I
saw listed for about $150 in a magazine not too long ago. What a deal! Thanks again.
