    I bought this a while back to fix a short on my truck. I finally ended up using it and the test leads didn't work with the 10amp. I tried, tried so many times to figure it out until I finally gave in. It just didn't work, so I took my hammer and took out my frustration on it. Great for stress relief, bad for what it's meant to do.
