The product worked well until it suddenly failed. Edit: Full refund from manufacturer under warranty, rating changed to reflect product support.

worked well but stopped working and is no longer accurate, the temperature world does not work when in the water with pH monitor

Yes, I could say that it is very accurate and inexpensive, but I would like to say that it is very easy to use and with simple calibration instructions to follow. Time will tell how often this is necessary. Hopefully fewer than others I've had for my indoor garden.

So far, so good. I've had it for over two months now. People say it can only do one thing at a time when your batteries are low. If it starts to fluctuate, your batteries are dead. I'm very happy with it so far and will buy another one.

For the price this thing works very well, although it's probably best to take it out and clean the sensor with distillate if you're going to use something to continuously collect data all the time read water every few days or a week and recalibrate if you're not getting accurate readings in distilled water, things like nutrient solutions or rainwater tanks can drop readings over time, but overall I've been happy

Arrived, tests showed that the calibration is unstable. Changes over time for an unknown reason. Make sure you calibrate when the device is at room temperature. The room temperature should be close to the normal daily temperature and increase if necessary. I tried minimizing the high-low edge and center to minimize skew. Has been connected to a backup battery with surge protection. Suspicious tolerances of internal components make the device prone to drift. I have endeavored to eliminate earth…

You must leave a review to activate the guarantee, also I give 5 stars because it did not disappoint. But boooo the company for getting you to do a check to activate that guarantee, boooo! Update: so failed on further use! I have contacted a company which by the way is a third party who has to go to another company to get a refund! I was asked to provide a "video" of their faulty product! The video I included is the video they asked for and I haven't received a response yet! For a week of…

So far this product does exactly what it says on the tin. I just received it yesterday and am currently using it. It says it works for long-term use and all you need to change after long-term use is the probe, so we'll see. Calibration was easy. It even had a conversion chart on the back of the solution if your distilled water wasn't 25 degrees so you didn't have to play games to get it to the right temperature, you can calibrate it at any temperature of your water. while the tempo was on an…
