Review on 🌱 Enhanced Accuracy RCYAGO Household Hydroponics Solution by Edgar Rowe

Very good price I've had one like this in the past and because I was working quickly one day while trying to measure, the glass part holding the liquid broke. Out of the box the new one was pretty much accurate. I've calibrated it just to be safe, which is something you should always do if you get one of these. Since then I've been using it several times a day and it has retained its calibration.
