Review: Simple and effective - Read the reviews where people describe how to best use this. I followed their instructions and it works fine. It's not a fancy piece of equipment, but it works fine. It saved my fern, which was in a "self-watering pot" that wasn't working, and when I used the meter it said it was completely dry. Another day or two of relying on the pot to water the plant and it probably would have died. Now I test it every day to see how much more water it needs, since a malfunctioning self-watering pot is just a stupid pot with no drainage. The meter is light-weight and seems a little flimsy, and I can't vouch for the complete accuracy or reliability, but I think for deciding whether to add more water to a plant (and approx. how much), it works well and is a good price. If I test the soil, add a little water, and retest, the meter goes up a little; if I repeat, it goes up a little more. Sensitive enough for my needs. Side note about self-watering pots for anyone who is interested: The kind with the inner unfinished terra cotta pot that is supposed to let water slowly soak through to the soil- test it before planting in it by placing the dry inner pot into the outer pot full of water and place a dry paper towel in the inner pot. If the paper towel isn't wet within an hour, the inner pot isn't letting the moisture through. I guess at this point you can try soaking it in vinegar for a couple days to remove any deposits that are blocking the water, then soak in distilled water to get the vinegar out. Or you can just return the stupid thing. Review: Very simple and easy to use - I was interested in a soil moisture meter that was very low maintenance and simple to use. This product is exactly what I was looking for. There are no batteries to worry about replacing or wondering if the reading you are getting is low because of low power. It works purely off of the chemistry of the water in the soil. Perfect and foolproof. The price was right too. I really like how the probe stores in the body of the meter... just insert from the bottom and you are good to go. The list of plants and their water preferences is handy, although not complete. Remember it is just a guideline and use your own experience to determine what is right for your plants and situation. The one improvement I do wish the manufacturer would make it that the meter needs a loop molded into the casing somewhere, so that a neck cord could be attached, thus allowing one hand to be free to steady the pot, or hold leaves out of the way, instead of having to hold the body of the meter. Overall great product. ## Features - Instantly tell when plants need watering - Measures water at the root level - Includes watering needs for over 150 plants - Product specifically designed to be used only in soil - No batteries required.

Relayed another way, if those who receive duds would believe those who write rave reviews, then, upon receiving your replacement wand, please say something karmically cool to our public, conveying good growth while causing the sales of this company to increase, ergo boosting its ability to cure the few defects they have, and thereby furthering the joys of foliage. I was mistaken. Within just 2 years, and with light use in my home, all three of these units were dead, defunct, malfunctioning, & otherwise trash. At $14 each, I believe that I'll be better to buy the old cheap ones, & that's now where I am heading! ## Frequently Bought Together - Luster Leaf 1820 Rapitest Soil Moisture Meter - XLUX Long Probe Deep Use Soil Moisture Meter, Water Monitor Indicator Sensor, Hygrometer for Outdoor Indoor Large Pot Plants, Flower, Gardening, Farming - VIVOSUN 6.5 Inch Gardening Scissors Hand Pruner Pruning Shear with Straight Stainless Steel Blades Orange 1-Pack --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/1096281-luster-leaf-1820-rapitest-soil-moisture-meter](https://www.desertcart.co.uk/products/1096281-luster-leaf-1820-rapitest-soil-moisture-meter) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
