This seems to work pretty well and is very easy to use.

The meter registers a reading of red (dry: 2 to 3)or the beginnig of yellow (4 or 5) no matter how much you water and even after dipping it in a glass of water.
Philip
Works great and helps you decide if you need to water your plants or not.

All the negative reviews I've seen are from people who have no clue as to what they're doing. You can't just stick it in water and call it broken. It works through electric impulses and with no resistance (i.e. soil) to those impulses you are going to have an insufficient reading. If you don't place it deep enough into the soil, you're going to have the same improper reading. I mean this thing isn't rocket science. I'm honestly baffled that so many people are having problems figuring out something so simple. It isn't broken, it isn't faulty, and it doesn't give horrible readings. It's the person operating the device, not the device in itself.

Here is how to use the meter properly.

-Submerge at least half of the meter into the soil. You may or may not choose to read 4 different points however for better accuracy of soil moisture I would suggest it.

-Water with half of the amount that you would typically use. Wait a few minutes to let soil drain down to the bottom. Then test the soil once more. If soil is still too dry continue to the next step

-Take the remaining amount of water and continue watering with 1/4 of the remaining amount. Wait a few minutes and then check the levels. Continue this until you're soil has reached the proper levels.

Years and years ago, my mother gave me one of these moisture meters to save me from over watering my house plants and ruining my floors and my furniture.
It finally died (probably after over 25 years!) so I purchased this one. What I like about this moisture meter is that it has a wand separate from the meter itself, which you can stick into the dirt. It makes it much easier to read than the temporary replacement moisture meter I purchased at my local garden supply store that has the wand extending from the bottom of the meter. I have hanging house plants and simply could not read the meter that way. So I highly recommend this one, which also comes with a guide that indicates how much to water a variety of plants. No more checking the top of the soil with my finger, thinking the plant needed water, and killing it with over-watering.

Style Name: Mini Tester
The first one of these meters I owned seemed accurate and reliable. I bought two more for convenience and have had a much less satisfactory experience. They both gave wildly inconsistent readings, rendering them essentially useless. They are particularly ineffective in soils with a high content of coarse material. A friend who also raises moisture sensitive succulents independently came to the same conclusions.

I'm very please with it after figuring it out, it works great - if others are having trouble, I hope they take the time to experiment a little to see if they're doing something wrong. The display is large, easy to hold and read, and you can use it on hanging baskets. or low pots, with ease.

After having one of the fixed probe models, i was really frustrated trying to read their small displays at odd angles, i had been wishing for something like this for a long time. I read the reviews carefully and was hoping that I would get one that didn't have the same issues as others were describing, plus i've learned that some reviews just aren't even reading the instructions that come with products!

The first couple of tries after opening the packaging, I was having the exact problems others described: never left "dry" mark, dipped it in water and it still said "dry". I was really disappointed and cleaned the probe off well, planing on returning it. Then, I read the instructions. When i stuck the probe all the way in (past 3") I started getting accurate readings! I'm wondering if cleaning the probe well also didn't hurt, but now it seems to work perfectly. I've used it a couple of weeks with accurate readings every time. The probe is a little "fatter" than my fixed probe and requires more force to get into the soil. I'm wondering if other users are not getting past the top layer of dry soil (like I was originally). Plus, when i put the probe deeper into a glass of water it does indeed read "wet".

Luster Leaf Rapitest Soil Moisture Meter #1820. Effective, versatile, accurate and inexpensive water meter. Convenient flexible cord permits holding meter in hand while probe placed in soil. Can be used inside for house plants and outside for larger plants and new shrubs. Cheaper if ordered from Denny and Kathy Ace on same page with Amazon direct order. Make nice and appreciated gift to people with garden interests.

Moisture meters start at about $6 and run up to well over $100. At first I bought the $6 type, the only kind at the local nursery because I didn't want to pay a high percentage of the product's value for shipping. It's sold by Amazon (with free shipping) as the "mini" meter. It was unusable junk just as the reviews indicate. Because I was turned off, I was reluctant to try this one (#1820) because it's still fairly cheap compared to the meters and irrometers used in commercial operations and research. If I needed to pay $70, even $200 or more, I would, and an additional 5% for shipping would be fine. I needed something that actually worked and not just a toy trinket to play around with. This one is quite inexpensive and though shipping was proportionately costly, I gave this one a shot and I found it completely satisfactory.
