 Rating:  - okay otherwise but ph testing feature uselessThis unit is very useful for measuring soil moisture and sunlight. While I wasn't in a position to evaluate the fertility feature, I do know that the ph testing is useless. When I tested the commercial soil in my potted plants, I noticed that they all indicated a ph of 7. To my surprise, my yard and garden soil also indicated 7.

It's not substitute for a good soil test, but I've found it to be a good indicator of when a soil test might need to be done. Rating:  - Cheap and useless.The one I have doesn't work at all, so I opened it up. The total price of all the components has to be less than $5, which makes $35 a rather outrageous purchase price. The components are the case, the probes, the meter, a 50 cent rheostat, a switch, a small photo cell, and a resistor. I can't see how that meager melange is supposed to produce meaningful results. Rating:  - all 4 in oneA very good device for the price. The only thing that I didn't realize at first was that the NPK numbers are not specifically given. Rather, the device gives you an overview of whether the nutrients are balanced or not. If the nutrients are not in the "ok" range, then you'll need to do a seperate nutrient test to find out exactly what the levels are.
