Reading is almost accurate.Highly recommended ### ⭐ Não vale o investimento. *by on Reviewed in Brazil 28 March 2021* Apesar de ser mais barato que em lojas físicas, vale mais a pena fazer os testes manuais msm. Coloquei o produto conforme descrito na embalagem. Além das cores não serem bem distintas, aparentemente mudou de cor apenas na primeira vez, mesmo eu tendo corrigido o pH algumas vezes. ### ⭐ 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.
