Outstanding spark plug tester and it has a good price point
Very nice tester. It is easy to use and will save you a lot of time trouble shooting. The tester is built nice and can test a lot of different types of plugs. The side by side saves a lot of time doing two at a time. Takes me around two minutes to test eight plugs. Now with the cost of plugs it is nice to be able to see them work after cleaning so no second guessing after reinstalling plugs. I did find a few bad plugs and two would have made miss fires at random times making it very hard to trouble shoot.

Great Tester To Check Spark Plug Health
A great little item to have in your DIY shop for testing plugs. First test I did with my Ancel SP02 was test the plugs on my old ONAN P220 mower engine to get it ready for this year's mowing. With the 2 test holes, it was perfect as I could watch both plugs spark same time. Noticed one plug was not as powerful as other so stopped test to see why. Did air gap measurement and found that weak plug's air gap was off. Did an adjustment and re-tested and ran the power up through it's paces. The higher the so-called RPM of tester, the noise changed in pitch to a high whine which I didn't expect. A good plug will spark blue to blue-white. If you see yellow, arcing out the glass insulator that you might not even notice from a crack, or plug has what is a dead spot (no spark) at certain RPM's of the tester it is time to replace that plug(s). Also, test all new plugs before installation. You'd be surprised to possibly find a bad plug from all the jostling around during shipment. Don't know why I hadn't gotten one of these years ago. They're also kinda fun to watch during the spark testing. I have a couple In-Line Spark Testers that work well, but this is better in that you can actually see the spark plug and what it's doing under a high RPM test load that a mower's engine won't get to and how healthy that spark is through the ranges the tester gives.

Must have
Absolutely love this tester! Changed some coils on a vehicle that had a misfire. Was able to very all of the plugs were good before reinstalling the plugs. For the low price, this is a must have for any garage!

Time saving tool
Instantly I found 2 spark plugs that were failing in the upper RPMs using this awesome little tester. Paid for itself right there. Just make sure the plugs are cleanly grounded to the tester grounds and you'll get accurate results.

Worth it
I have to constantly replace sparkplugs does i need to know which ones work. This product serve its purpose.

One out of two worked properly
My first one was inconsistent. I initially attributed the aberrant spark performance to the spark plugs as I had gotten some cheap ones with a small engine rebuild kit. However, I ended up getting a set of new high quality NGK iridium spark plugs and played around with it only to realize that one side of the tester was inconsistent. I bought another because I really need to be able to test plugs and this second unit seems to work properly. I would have returned the first unit had I realized it was defective early enough.
