Easy to use. Good instructions. Only takes a few minutes to do a test. Hanna quality is great. Makes it easier to test your phosphorous levels. Not a bad price either.

Sold me a used kit. I only just opened it now because I finally got my tank cycled. Everything is opened and used.

Bought this so I can calibrate my auto tester. Super easy to use. Clear instructions. Repeatable results. Bought all 3 testers for the parameters I test for regularly.

I have other Hanna digital instruments to take care of my pool. This is totally unreliable. Got different samples of pool water using the 2 provided bottles. One with clean salt water for reset the C1 value and another one with 1ml of solution as requested dor the test for the C2 results. Every test gave me different results ( from 0 to 51). Pool pump worked all day long with fountain as well to be sure water was not still water.After 3 tests during the day and different results I returned this product because or it's broken or it's ineffective. I measured later with a professional (L1 level) digital instrument the real value was 151ppm.
