I like the unit, grounding/shocks were a pain at first but I figured it out. for $60 it's tough to beat. it's like a lot of diagnostic tools, you really need all the engine systems in good shape and working properly for it to be useful.

Don, it's been a while but this is a useful thread. I understand the value of interrogating individual cylinders and their respective idle circuits and am going to see how close my lean best tuning got me by comparing with a Colortune. My guess is that I am, in fact, lean.
Are the grounding shocks from positioning the mirror? Do you have tips for installing/removing the unit?
