• Meters are color coded for simple pass or fail diagnostics
• 15 second test with audible tone

Ease of use is low. It arrived with the knob loose so I simply tightened it with a allen wrench. Serves it's purpose.

I wonder what copper stand cables are??

UPDATE: After a few years, it started making a rattling noise inside. I opened it up, and found 4 loose nuts, one fell off and was the rattler. The cheezy box protects it well, but is falling apart.

After using it several times, I finally memorized the instructions. It always does a very good job of telling me the battery's condition. Hook it up, load to half the cca, 15 seconds to test, fairly simple. Just make sure the load knob is all the way off when attaching and detaching or it will spark like mad.

I tried to change from 3 to 4 stars, but it won't let me.

For the cheap price, it may be good to do the odd battery load test, but adjustment was finicky and it started sparking inside sometimes.

The pro's of this tester are the ability to adjust amperage load. Accurate testing of a wide range of CCA are possible with this tester.

The cons: The tester performs it's functions; however, it seems cheaply built. I haven't had it long, but the "carbon piles" seem very fragile and destined to break. I run a mobile mechanic service, and I was afraid to put it in my truck. I move it around real softly afraid I'm going to break it. The adjustment knob seems really cheaply made also. It doesn't seem to adjust real accurately either. After you stop turning the knob, the needle will continue to rise sometimes.

All in all, it seems to be a very capable tester although cheaply manufactured.
