Review: Working pH probe - Product came in a sealed box with a working pH probe
Review: Accurate reading. - When I first started using the meter every time I took a reading I had to calibrate the probes each time I used it, now I keep the probe in the aquarium on a permanent basis it saves a small fortune on buying calibration powder and distilled water, also gives a more accurate reading than the coloured chart type of tests.

*by A***R on 30 January 2025*

Doesn't work properly, keeps freezing. Screen malfunctions. Can't seem to get a replacement. Probe broke very quickly. Bought a replacement. Realised the unit was dodgy too. Waste of money. Would like a refund.
