Query: Much better than expected

I considered trying one of the gadgets that pop into a holder to test the batteries, but some reviews stated they were inconsistent in results. I ordered this battery tester and am very pleased. I'm getting consistent results almost every time. My problem is holding the battery still enough on the contacts while the results are determined. I'm also pleased that it measures the battery with a load test.
