I will second what George just said. Better test kits are worth the money! I have noticed with the cheaper kits with only one or two reagents for complex tests tend to degrade over shorter periods of time, while the better kits that have several reagents in separate vials are more repeatable over longer periods. Also, the titration-type tests that Lamotte frequently uses are *much* easier to read than the color chart tests, IMHO. Sooo much easier...

I've had good luck with some of the little Tetra kits but I like my Lamotte kits better. You get better labware with the better kits that both makes the kits easier to run and last longer (refills are cheap).

And better accuracy is always a good thing :-)

What about people who live in the UK (like me) or other countries? I use the Hagen kits, but do Lamotte and Hach ship abroad?
