Important for plant maintenance.
Worth every penny to make sure plants are moist enough. Easy to use. This product will last me 10 years, I know it. For indoor and outdoor plants. An important meter for outside gardening.

Must buy
This tool has saved me multiple times in my gardening journey. I was able to see just why my plants weren’t growing the way they were supposed to and when I added worm tea to the garden, I was able to tell that the problem was on it’s way to getting fixed. Definitely sound thing every gardner needs

Affordable Soil Meter, Light Meter Not Very Useful
I'm very new to owning houseplants, I tried my hand at it back in college and it did not go well. I bought this to help me keep an eye on the soil conditions, as I feel that my previous failures have mostly stemmed from underwatering and lack of fertilizer/nutrients. After experimenting the moisture, nutrient and pH functions of the meter appear to work very well. I will still likely use my finger to confirm the moisture readings as I know overwatering can be a common issue as well, and one of my plants already has root rot (came to me in this condition), but this meter definitely gives me some peace of mind to be more confident in my watering schedule than I would be by just feel alone. Paired with a plant care app on my phone (Plant Parent: Plant Care Guide) I think I'm getting the hang of things. My only complaint is that the light meter doesn't seem very precise (what are the numbers on the dial anyway, lux, foot candles? I can't tell) and I've only been able to get it to go from 0/dark in any type of indirect lighting to the max reading when moving it to direct light. I've never been able to get any readings in between. Fortunately there is a really good phone app that measures foot candles (Lux Light Meter Pro on Android) and some guides online (House Plant Journal) that tell you about how many ftc each plant species needs to survive or thrive so that has helped fill in where this device is deficient. It would be wonderful if the light sensor was more sensitive but for the price, I feel like this was still a pretty good deal and I'm glad I bought it.

Every plant lover should have this tool.
I am a plant lover. This tool is very very helpful to see when to water my indoor plants. Otherwise it's hard to find out, did I over watered or less water to the plant. Every house must have this . I bought this 3 or 4 years ago. Never have any issues. So it last long.

Not Easy to Read, plus deceptive switch
I only wanted to know the soil PH, and the indicator for that reading is right at the bottom of the dial. It shows up as a line, rather than a dial. Perhaps having 4 uses for one tool might not be a good thing. You have to read the quick start guide (aka manual) to understand how to use this. Since this has 4-in-1 modes, you will need to move the switch to get the correct reading. There are 4 switch settings. Reading the manual you will find it has a useful list in the back with plant PH info. and what plants require for each setting. An online version of this would be helpful. I tried testing the PH of rainwater collected in a rain barrel a few hours earlier and it said it was 5 to 6 PH.

A PH and LIGHT “ READER “
I really like this item. I’ve tested it using the PH MODE so far several times on a special new plant which requires acid soil. So far. the “ reading “ is the same, even though I gave the plant an acid fertilizer recently. Today I added more acid. If it continues to “ read “ the same, I will return it. Time will tell. I’m quite an experienced gardener, so don’t need to mess around with silly tools.

Amazing product
Amazing tool! Our garlic started to turn yellow after winter. We feed it regularly, but still it did not help. Bought this, check soil. It turned out that soil PH was to low. Use it all garden now. So easy to use. A must have for every gardener,

Awesome tool for plant lovers!! 👍🏼🪴
I bought this "Sonkir 4-in-1 Soil Moisture Meter" almost a year ago and have been using it weekly (sometimes more frequently). Highly recommend this moisture meter - it's a fantastic tool that's saved me from overwatering my lovely plants!! 🪴 I wanted a "no-battery manually operated" meter such as this one (very convenient). I also noticed some of the 3-in-1 or 4-in-1 meters have two prongs instead of one prong like this - since two prongs make it more challenging putting it into your plant's soil without disrupting the plant's root system, opted for this meter and am super happy with it. I no longer have to stick my finger into the soil to check moisture levels and even better, this probe reaches quite deep since often the soil might seem dry at the top couple of inches while the soil is quite moist/wet when it's a few inches deep and you don't want to overwater your plant which can cause root rot 😕 I've also used the meter to check PH levels and light levels which is very handy.....admittedly, I'm not sure how accurate the meter is at determining nutrient levels since I did have one plant with slightly yellowing leaves and it ended up needing a bit of fertilizer (the nutrient meter reading didn't pick up that nutrients were lacking in the soil for that particular plant). In any case, I would repurchase this Sonkir moisture meter if I lost it and certainly recommend it!

Sehr hilfreich im Garten
Sehr hilfreiches Gerät um den PH Wert und den Nährstoffgehalt zu messen. War erst skeptisch aber funktioniert sehr gut.
