After using this for 6 months for and comparing it with ordinary test strips I am very confident it can deliver accurate readings and, as has already been noted, it is good for spotting trends. 20p per test strip is still quite dear but the digital readout makes testing on dull winter days far more accurate than eyeballing a colour. Having a digital readout makes judging chemical quantities much easier and for me it earns its keep on that account alone.The test takes about 15-20 secs to complete and whole process is very simple.
