Worked exactly as advertised..
I suspected I had a rich mixture so I bought this. I followed the instructions and I adjusted my mixture until I reached the target CO spec (for an older Porsche 928) and now the car runs better than it ever has before. I recommend.

Works well - read the directions!
Works well for tuning vintage autos, but read and understand the directions! Proper calibration is key - this isn't a toy, you have to think about how you are using it.

Decent analyzer; seems a tad expensive
The unit is a bit cheaply made (plastic), and not robust at all. However, it seems to work OK. Has sufficient length power cable and the plastic exhaust tubing is long enough. So far the plastic tubing hasn't melted. The CO readings seemed to fall in line with what the NJ state inspection station reading for CO was. I have only used it twice, and will revisit to adjust my rating at some point down the line.

Cheap build quality for the price
Calibration knob was broken out of the box. Very flimsy build quality. Didn’t get to open it til it was out of the return window.

OK for the money
Requires a lot of warmup time, about 30 minutes, to get accurate readings. It's also a bit flimsy. Not bad for the price paid.
