Luster Leaf 1662 Professional Soil Kit with 40 Tests, Green

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.

I cannot use this kit. I have tried and failed. The filter comes off, the solutions sit, without changing colour. Not sure what i am doing wrong.

Box arrived damaged but, contents were fine so, wasn't overly bothered.

It can't be used for 40 tests only 10 max

Good enough for average backyard gardener. Yes, it's not as accurate as sending in a soil sample. Takes a little getting use to use, but gives you a general idea of what and how much to amend to your garden soil. I have black, hummus rich, loamy garden soil (it's very pretty), but am depleted of nitrogen and potassium. I had amended in spring knowing my soil was likely deficient, but I didn't realize I wasn't amending enough nutrients. My high intensity garden is 350 sq ft in size. The instruction and info sheet included was insightful with how much I should be amending based on test results. Very happy with end results. Will order again when I run out of test solutions in the future.

The item was just as described, Easy to use, repeatable results. Told me what is needed for a good healthy garden. Thanks

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.

Product was faulty: pH bottle had leaked. When screwing the plunger down on the filtering device, the O-ring was displaced from its nested position in the plunger. I replaced the O-ring 3 times, but the same thing happened. I watched several videos on using the soil tester, but was unable to match the resulting nutrient test colours with those in the reading colour charts -- N test repeatedly was green (once milky white), should have been a shade of pink. P test changed from Depleted to Surplus within 20 seconds while waiting for solution to settle. Could never make any sense of the K test results. I emailed Luster Leaf for clarification of instructions and advice but they didn't reply
