Fast delivery! Works great! You only need distilled water for calibration, then nothing stands in the way of the measurement! The eyepiece is adjustable and can therefore also be used by people who wear glasses without glasses. The measured values seem plausible to me, but I will still carry out a comparison measurement. The device is definitely worth the money!

I used it a few times now and its not good at all. I put it in the dark and then right under a huge grow light and it didn’t change. Other than that the ph meter never reads anything in the soil. Its always marking 7 and my plants ended up suffering from bad pH in the soil. I tested with another meter and the soil is now pH 9. Do not buy this item.

Works but even once calibrated the device does not display the correct measurements, disappointment. After a week of use the equipment still does not work properly it's just a scam I ordered a new one on a culture site and that's something else it works perfectly !!

Was barely able to switch the screen on after installing the batteries. It was just flashing green, dimming in and out, not displaying any values. After not even reacting to the power button at first. After some fiddling with the battery connections it at least switches on, and seems to work relatively good for now.

very good quality. the screen is very clear and easy to read. background light is very bright and turns on once you plug it in, turns off a few seconds later. easy to set the settings. tried it on many different apliances. hope it works well for a long time. P.S. seller sent along a small gift - a SIM card pin.

I do not think the ph measurement is accurate, tested in my aquarium, it stays always at 7. The light and moisture sensor work satisfactorily. I do not understand how the device works without batteries.
