Is this kit for a one-and-done test? If so, where and how much are refills for this product?

This test has several capsules for each test you want to run. My soil was really depleted. So I tested the first time to see what it needed, and then added those nutrients, and a week later tested again. I used the recommendations on the instructions to "fix" the soil, and it worked really well. The kit is easy to us. Read the FULL INSTRUCTIONS on the inside. The short version does not work. It will take a few hours or even days for some, because you have to put the soil in "purified" water, and let the soil settle to the bottom and the liquid become as clear as possible. I bought these on Amazon and if I remember right paid less than $10 for the complete kit. It was cheaper that way. I love these tests. Hope this was helpful.

can you use it for several seasons.. or do the chemicals go bad once opened to the air?

The chemicals are in capsules. I used mine throughout the season last year on multiple foot plots around our property. Each variety of capsule is in its own sealable baggie also. You should be good as long as you keep them away from open moisture.

how many capsules do you get and how easy are they to find?

There were 10 capsules for each test, easy to do, and fairly accurate I think. I'm a science teacher and have used this type of test before. They were color coded and in separate bags.

Can i get spare capsules for the tester on amazon?

If you want to test across multiple seasons, look for "Luster Leaf 1880 Rapitest Tester Electronic 4-Way Analyzer, Soil". The meter can be used over and over without regard to having any chemical capsules to use.

Easy to Use

Easy to use and accurate enough for residential use.

A bit fiddly but reliable

It shows pretty close results compared to professional lab test. What type of nitrogen it is testing for would be good to know though. To apply the test capsule reactants to the tiny test chambers is a fiddly, fumbly business. There should be a kind of hopper coming with it, especially since the base of the test containers are not designed for a stable stand. I tried to find out wether you can buy replacement capsules. If I have to buy an entire new set after ten tests than this is unsustainable plastic waste.

Tut was es soll, funktioniert, kann natürlich nicht überprüfen, ob die Testergebnisse stimmen.

Works but instructions not completely accurate.

Great kit altogether, super convenient. I found that it took up to 12 hours for the solution to change colour completely, so be patient.
