This product is a bad plant mom’s dream! My plants are thriving now that I know how much water they need. I also use this device in my garden and with my new baby apple tree. Very helpful and easy to use! ### ⭐ Terrible and unreliable *by B***B on April 12, 2026* Rather useless and doesn't read anything correctly. If you were to rely on what this thing reads you would be sorely disappointed as you will probably apply too much of the wrong stuff to your lawn or plants. ### ⭐⭐⭐⭐⭐ it works for water levels. *by D***A on October 23, 2025* I had been looking for something, so I researched and researched and couldn't find anything definitive on which brand would be best. I finally took a chance and purchased this one. It works. I think that is what most people need to know. You just stick it in the ground, and that's that. But, it specifically states not to use it right after watering. Follow the directions and you should get a pretty good read on what your water levels in the soil are. PH, I couldn't really tell what it was telling me. It all reads from the same meter, so.... I needed it for the water, so decide what you need and then decide which item to purchase. So far it still works and I keep it with my garden tools. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/312949870-suplong-3-in-1-soil-moisture-meter-upgraded-stainless-steel](https://www.desertcart.jp/products/312949870-suplong-3-in-1-soil-moisture-meter-upgraded-stainless-steel) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-15*
