Title: Worthless
Review: I bought this tester last year. I too had read the reviews and cautions about the importance of following the directions. I am that guy - it's a curse. I concluded that I got a defective unit, and Amazon made it too difficult to return for the money. Now I'm shopping again; and it seems that there is a serious QC issue with this company.
