Good purchase!
Very comprehensive water testing kit. Easy to use and results are clearly displayed. I had a small issue with part of the testing kit which was completely resolved, very quickly and without any difficulty by the supplier. Regarding the bacteria testing vial, I’d recommend to measure the water into a 5ml spoon or container first and then pour into the testing vial as the vial fills up extremely fast from the tap and could overflow. Both the product and customer support deserve 5 stars! Would recommend.

Gave results that seemed accurate within precision window offered
I used this to test the tap water in Budapest. The water quality tested good except in three respects: high ion content (hard water) which I already knew; very high acidity which I would like to re-test in case it is a spurious result (I do not understand why the water would be extremely acidic) and unacceptable level of pesticides, which was a surprise. However after doing some research online I discovered that Budapest has a problem with pesticides leeching into the public water supply (there are scientific articles about this, one I came across produced by the Hungarian Academy of Sciences, a very highly regarded institution) and therefore I now find this positive result quite plausible. I thank the test for alerting me to this and now insist on buying bottled water for drinking, coffee, etc (although that comes with other problems - e.g. leeching of pthalates from the plastic).

Worked, but very expensive.

Avoid
Avoid this product. Expensive and not fit for purpose. Instructions unclear causing confusion when testing. Only allows to test one sample of water. Very poor value for money.

Comprehensive, Easy to Use, and Good Value!
The test kit arrived very quickly, and in good condition. The instructions for the various tests were clear, and concise. It was very simple to check the results, with little possibility that one could misinterpret anything. The kit included every relevant test for a domestic well water supply. It represented good value for money, and I would have no hesitation in recommending this product.

Seems accurate
Without physically testing alongside an actual laboratory it's hard to say does what it says on the box, but it had visible readings on the dip sticks and colour change on the bacteria test so gave me the comfort to use the water in my new house. So far I'm not ill so must of been correct.

Poorly written instructions, flimsy
Poorly written instructions, the kit is flimsy. I would not recommend. I was expecting a quality product for the price.

Seems to work !
A number of tests, most can be completed within 30mins but the bacteria test takes 48hours for results. The tests from my well water came back OK ! So I can only assume that this test kit, which is thorough, is accurate.

Seems to have worked well
Seemed to have worked well. The only thing I noticed was that the pH strip changed from 6.5 to 8.5 a few minutes after I'd completed the test and set it aside, but both of those numbers were within acceptable limits. Still waiting on bacteria test as of this review, but we get that test done by the municipality and it showed a 0 when we did it a few weeks ago. The only issue we seem to have with our well water is Hardness (120ppm). Other than that everything was either zero or very very low.

Ottimo test
Tutti i risultati sono stati in linea con quelli comunicati dal nostro acquedotto, compresi i due un po' "fuori scala"che ci aspettavamo ovvero durezza e ph, con i quali l'acqua del rubinetto resta comunque perfettamente bevibile e potabile, quindi da oggi si dice basta all'acqua naturale in bottiglia. Tutti i test sono semplici ma occhio che non ci sono istruzioni in italiano.
