Review on 💡 Controller Electrode for RCYAGO Hydroponics System - Easy Replacement Option by Brock Chisholm

I often try third-party alternatives that are cheaper than their regular counterparts. In this case I bought it instead of a traditional Milwaukee pH controller and was disappointed. Device issues below: - The instructions are absolutely terrible, the English translation is hard to decipher and not very detailed - The wireless monitoring app is not a registered Google Play app, so there is no security verification. I don't want to download it on my android device due to the app source. I have never been able to calibrate the device using the instructions and the standard 4.00 and 6.86 calibration fluids. All in all it was wasted money. I'll try and return it, but due to the time between purchase and actually trying it, I doubt I'll get a refund.
