## Customer Reviews

### ⭐ This is useless.
*by  on Reviewed in the United Kingdom 11 April 2016*

This product does not work only shows a beige colour that is not one of the colours on disc even though testing with liquid testers and electronic calibrated testers show water to be exactly 7 pH which should show as orange on disc not beige. This is second one bought as thought first one was just a faulty card but results exactly the same. Useless!

### ⭐ Don’t waste your money
*by  on Reviewed in the United Kingdom 29 July 2025*

Only worked until I did a water change

### ⭐ Disappointing
*by  on Reviewed in the United Kingdom 24 August 2020*

The colour of the circle was never matches on the dial. Despite changes to pH in test stripes. Not worth the money and I use other seachem products that are excellent, so disappointing
