I've used them, and they are about as reliable as the aquarium pharmaceuticals test kits. The only thing good about the hagen master test kit is the case though. Since it comes with almost every test possible, you are spending over $50 for what is essentially a really nice case. I don't ever use the calium test, the high range pH test, or the iron test. If you can get it for less than $50 (i got mine off eBay for around $30 half used), then it is a pretty good deal. Like I said, the only real benefit to having the master test kit is the really nice case.
