VXSCAN Automotive Spark Plug Tester with Adjustable Double Hole Detector Car Ignition Analyzer

It works good and better then I thought

The media could not be loaded.  Love it, Works as it should,, so what if the knob calibration isnt exact below 2000 rpm,it doesnt matter. The spark is still accurately adjustable from start to max rpm. Cant beat it for the price. I do not represent anyone, its my honest retired aerospace mechanics opinion. Tested a dozen plugs for a half hour b4 posting this feedback..also arrived in 4 days with amazon prime . In a perfect world I would like a stronger spark, but then it would a health hazard and need a possible death disclaimer so i understand why its intensity is what it is..its more then adequate for testing for a bad or misfiring plug..the next better tool similar too this starts at $300,,so this would still be a bargain at 100.. also every automotive and motorcycle plug i own fit in it fine. Tiny short plugs dont reach the contacter inside down in the bottom of the box,,but 1 min is all it would take to make a spacer out of proper diameter copper tubing for any plug you needed to test..

I so wanted this product to work as it's such a cool idea. I tried three different units, two came with one plug hole not working and the third came with the rpm adjuster not working. Quality is sub par. Save your money and time.

ok

This product is a deceit, it does not come for all the spark plugs (Practically you do not see that it comes for 11mm buias), a total Fraud
