As an Automotive Technician with 41 years experience I found the meter simple to operate , clear display, bang for buck and the luxury of cable length is awesome
Very useful when using on multiple vehicles
Use device regularly great quality excellent for tuning very precise
I’ve used just about every carb balance contrivance known to man and always seem to get water or mercury sucked into the engine,
This thing is the best ,
Quick and easy and spot on results 👍😃
Its a joy compared to plug chop style tuning ,chasing jetting and mixture settings .
The only improvement i could suggest for people with lesser experience is more information in relation to using it in the manual and i haven't found yet any info online utube etc .
Other than that ..definitely money well spent
