PH test worked somewhat. All other tests resulted in N0, K0 and P0. Followed instructions perfectly. Even tried testing soils extracted from potting mix - still all zeros. Beware, probably many faulty batches. Very Poor experience, and many hours wasted.

Super das es dieses Set mit den verschiedenen Tests gibt. Ich benutze es im Kleingarten um rauszufinden was meinen Pflanzen fehlt, natürlich kann man auch an den Blättern der Pflanzen erkennen wenn Mangelerscheinungen auftreten aber damit das garnicht erst passiert ist es gut wenn man vorher weiß was dem Boden fehlt. Das funktioniert mit dem Set sehr gut, man muss sich nur ein wenig damit befassen, und wenn man es einmal ausprobiert hat dann geht es beim nächsten mal auch leicht von der Hand. Anleitung leider nur in Englisch aber anhand der Bilder und mit g... Übersetzer auch kein Problem. Würde es erneut kaufen. Klare Kaufempfehlung.

The instructions state ""You may feel strong resistance while filtering" I did... then heard a crack and the cylinder body has an inch long crack. I managed to complete the N test and the P test, but on the K test, the soil solution was leaking directly into the filtered collection tube. Not sure if a manufacturing defect or just being over butch, when not knowing exactly what to expect. Please advise how I get a replacement filtering device, the website won't open for me, and I'm outside the Amazon return period. The tests themselves are reasonably straight forward and the N and P tests returned valid results.
