For any handy DIY home owners in a warmer climates, I didn't buy this one as a gift for my brother because it doesn't do capacitor testing.

AC units can have capacitors that go bad and it's a fairly cheap part to buy and replace yourself. Versus an AC repair person that's typically over $100 for the visit and then whenever they want to charge you for the capacitor on your AC, that isn't working.
I have a Klein volt meter, a step above this that does capacitor testing and I was able to save myself a AC repair person visit and put a new capacitor in for $35.

My AC wasn't kicking on the compressor and it was due to an old capacitor. I was able to fix it with a voltmeter, a YouTube video and a screw driver.
