The meter works as stated and I'm very satisfied.

This thing is pretty cool and I think some plants may have been saved from the graveyard if I had this sooner. There is a little button to switch modes and it’s an instant read. The only thing is that the light sensor can only interpret how much natural light there is. I have a plant grow light with the UV spectrum but it didn’t register at all on this, I took it outside to make sure it worked and it does, the needle immediately shot up to high light. So if you were hoping like I was that you could test the usefulness of your artificial lights, you cannot. Otherwise great value and saves some time when checking on which plants need water and no more guessing if the soil is right for the plant. I think this is a must have for anyone who has plants and isn’t a savant who can just look at a plant and know what it needs. February 2024 update: my plants are thriving since using this to find out all the soil needed more acid. I switched what kind of plant food I was using and now just about every plant has exploded with growth, almost every one has multiple new leaves and is a more vibrant color. The only ones that don’t are the “slow growers” but they will eventually now that they’re getting the right nutrients.

Easy to use and to switch between each feature. Reading the face for moisture is difficult unless you can kneel down or really bend over. Better to see where the needle stops and read the number after you extract it. I don't need a number. I want to see motion from dry to moist. Amount of light measured, added little value to this device. The pH can be useful if you have the knowledge to change it. It looks impressive when you are using this double probe measuring device to someone watching you. It is a valuable tool for the gardener, speaking as a gardener.

I learned that I needed one of these and started to do some shopping here on Amazon. Talk about OVERLOAD! If one isn't really knowledgeable because it's your first time needing one, it is OVERWHELMING trying to pick ONE that meets your needs, doesn't cost an arm and a leg and just isn't complicated. This is EXACTLY what you need if you are using soil. Works great, easy to read, accurate, easy to clean, seems durable enough, no problems there, not cheaply made. Everything I need, not complicated or expensive! If you're looking for that, this is a great find! I totally recommend it! If you need something for hydroponics or anything more complicated, this would not fit your needs!

I purchased this as part of a bundle, needing to add a thermostat to my Vivosun heat mat. From the moment I looked at the packaging, I knew I was in trouble. The packaging is shoddy and I recently bought a pair of pruning shears with similar packaging that fell out of their packaging in the shipping box. Multiple misspellings on the back such as "Cladium" and "Ferms". I immediately tested the moisture in my Spathiphyllum which I knew I just watered with distilled water and it tested "Wet", then I watched the arm slowly swing to "Moist", which pretty much confirmed my suspicions about this "device", but next I tested the pH meter. All my plants tested ~7 (the default for the device), which is odd because some of them are potted in pure peat, so then I ran some experiments. Our tap water is about a 9 and clearly vinegar is not "6". The measurement of 6-7 doesn't vary much no matter what you do. Ironically, the light sensor appears to be accurate, which is funny because that's precisely the thing I don't need - save your money and download a free light testing app instead. Strong carnival prize vibes coming off this thing. Will be returning.
