Query: Doesn't Work, Save your $$

I bought the Burpee Electronic Soil Tester at a local nursery, thinking that this must be a functional product or else the nursery wouldn't sell it. Following the package directions, the dial didn't change much from the off position in either the pH or fertility function. I though I'd do an experiment and dip it in lemonade. In pH mode, the dial moved to max pH (alkaline), not to low pH as expected for the acidity that lemonade is.Then decided to look on Amazon to see any other feed back. The one other feed back on this product from J.Hill had same results.Not a good product. Recommend avoiding.
