Review on 🔍 Innova 3420 Smart Test Light/ Circuit Tester: An Optimized Solution for Efficient Searching by Chef Deane

I am a qualified car mechanic and use this LED test head at least once a week! It's been years and this is my probe. Very durable, I've even come across it a few times. he seems indestructible. The only thing that bothers me is the lack of an option to change the tip, and the stars are almost nothing to lose because of it. A quick trip to the mill and it's just as spicy as the day I got it!
