This moisture meter works just fine. For all the reviewers who stuck this moisture meter in water and claimed it was junk because it read "dry"--(*facepalm) that's not how moisture meters work! Such devices are designed to measure the electrical conductivity in soil, not the "wetness" of water. I haven't ever met a moisture meter that would read water. For those who said that they just watered their plant and it still read dry... I would wait a good hour and test again. Depending on the type of soil (many types are quite hydrophobic, especially when bone dry), it takes a while for the soil particles to absorb the water. Sometimes seeing the water draining from the bottom is not enough. It can run right through if the soil is bone dry. Let it sit and water again after 30 mins. Then wait a while and test again. Another possibility on that one would be that the soil was so saturated with standing water, the meter could not read the soil because it only had contact with water (similar to what happens when you place the meter in a glass of water). Anyhow... I've used moisture meters for over 30 years, and this one is as accurate as any I have had. (Though I expect they're all manufactured in the same factory in China, so...they're all essentially the same.) I use it mostly for houseplants, a range of different types, and the meter usually reads in the dry or moist range. I rarely see a "wet" reading because I generally don't read plants that have recently been watered.
