Tetra Test 6 in 1

Roughly the result of the water quality, however it lets me know if there is a problem.

Well. But dark colors tend to rub off on neighboring squares, making their interpretation imprecise.

Good product works well and easy to use Received the product on time

Always reliable test. I use it once a month to check the condition of the water in my aquarium.

Very good product, it helps :) not as good as the tests in drop but level quality price for tested the advanced of a break in aqua it's great!

test cheaper than the drops but lacks a bit of precision otherwise does its job
