  1. Coil Master Ohm/Volt meter 5 Star Review

    Posted by on Sep 20th 2018

    When I saw this on here for $0.99 I seriously didn't believe it. I ordered expecting it to be a piece of junk that didn't work or have some kind of issue... but it actually works great! I'm shocked... There as absolutely no other place where you will find a deal like this... Even at it's original price of $7.49 it was still a good deal. At this price you would be a fool not to grab one. Unbelievable value!

    Came nicely packaged. It's nothing special but I promise it gets the job doneand is accutate. It requires 2 AA batteries

    First build was off by .05 ohms between the mod and tester. Realized it may have been my own fault. Hasn't been off by more than .01 since. Great deal imo
