Great price for a well rounded tool
So let me start off by saying I thought this would be a tool I don’t use regularly but I was WRONG. As a mechanic I’ve used this pretty regularly the past few weeks and it’s helped diagnose some cracked plugs that couldn’t be seen by normal means. The quality is not bad at all for the price. And it’s become and all around great piece to add to my toolbox

Very good!
This bad boy is pretty neat. I had a pair of OEM ford mustang spark plugs. They were the original spark plugs that were on the car since i bought it brand new. I tested them alongside a set that I bought here at amazon with a full set of coils. The new spark plugs were performing noticeably better than the OEM spark plugs. This is a very useful tool hands down. They remove doubt when you have second thoughts of the spark plugs you are buying. The best part is they don't break the bank.

Great addition to your toolbox
Im surprised. This thing works great. I didnt think there was such a tool. This really helps find those good spark plugs in my stock. Never again throw out those mystery plugs without checking them. Great value for the money. Easy to use, put the plug in and turn it on.

Money saver
Wonderful for the price, it works great, so easy to use. Fits most but not all sparkplugs. So keep that in mind. Comes in hand when you need to test a plug instead of guessing and buying new plugs for no reason.

Good tester
Works good, but be careful for contact inside will bend easily

seems like a must have, especially if you have a ford f150 that burns up spark plugs...

Compré el ANCEL SP02 Spark Plug Tester para revisar el sistema de encendido y ha sido muy útil. Es fácil de usar y permite verificar rápidamente si la bujía está funcionando correctamente. La construcción se siente sólida y cumple bien su función. Una buena herramienta tanto para uso básico como para quienes hacen mantenimiento automotriz en casa.

It works, sort of, but it's difficult to make a solid connection and grounding to the tester to work.
