At first, I tested the unit in an acid and in an alkaline, and the indicator moved between 6.5 and 7.5. I thought perhaps the unit needed calibration (as I have the fancy-pants unit requiring a battery), and searched for Ferry-Morse online. You can't find a FM website, because the company was sold to Jiffy (maker of gardeners seeding pellets and trays, etc.) in 2005.
The unit seems to work for some people, but if it doesn't work for a similar number, as indicated here, it's like taking your hard-earned cash and putting it on a roulette table. Do you want to do that with the food you're trying to grow?
I'm going to return this unit, and put that money and a little more, on something dependable.

Excuse my english knowledge. Every time you use the tester you most clean it if possible with a fine sand cloth in order to a reliable reading ie. if you test vinegar give 3 and so on. You most read the instruction and follow it worth the price and utility

I should have known something that didn't even require batteries would be junk.
I fallowed instructions to the letter and this meter, no matter the conditions, it barely moves one way or the other. I wanted to see if I was right about the product so I put it to the test. I put it in pure wet fertilizer and it barely moves off center. Put it in a lemon and it shows a ph of 6. Put it in a cup of baking soda and water and it has a ph of 7, yea right.
Don't waist your money!

An acid or a base will give a charge, and this item shouldn't need a battery for that. That said, in college, we were taught to calibrate things with liquids, with a standardized pH. White vinegar is about a 3, ammonia from a grocery store is about a 10.
The medium, whether moist soil or a liquid, shouldn't matter a bit; if anything, the jars of vinegar and ammonia should read faster, and be more accurate!
This cheap thing stayed on 7, and bobbled back and forth between 6.5 and 8. No real difference whether I tested it in vinegar or ammonia.
Scientific verdict? Junk. Give me a no-stars option, and a no-bars choice for my review, please.

The readings on this meter never moves past 7 or 6 no matter what you do. It is truly worthless, I threw it away.

Product worked for me, was easy to use and very helpful in finding out what my soil needs. Not sure what happened in the other reviews. Maybe it was another persons item like in the photo from a review. It is not the same as this item.

I'm not sure why all the other reviewers are having trouble getting accurate readings from this device. Before testing my soil, I did some semi-scientific testing to see if the device actually works. In short, it appears to work as advertised. I immersed the rods in vinegar (a known acid), and the pH meter jumped down to 2. I then immersed the rods in soapy water (a known base), and the pH jumped to 9, wihch is the maximum alkaline value on the meter.
When I tested my soil, some areas of my yard showed as roughly neutral (~6.5-7 pH). Others showed as slightly acidic (~5 pH). I tested each hole several times, and achieved consistent results with each test. In my book, that shows that this device works.
Some of the other reviews mention the device breaking easily. What, are you jamming it into the ground with the force of a thousand earthquakes? It's made of plastic. I's obviously not industrial-grade. In fact, I'll knock off a star because it does feel a bit cheap. But what do you expect? It's a $10 product.

I meter kept reading 7 no matter where I put it, and one of the prongs kept sliding out. I'm new to gardening, but based off the other reviews I'm pretty sure this product is a dud.
