Which test kits are best?

[captain nemo]

I am looking for help on which test kit brands are better than others. This might be against the (post rules) as far as naming brands, not really sure.
Neither of the kits I have now are out dated! Both have a year or better left.
I have a Red sea ammonia kit. It reads .25
Than I have Salifert kit. Its Reads zero.
Makes you wonder......... I rather not give the rest of tanks levels because I don't want it to have any influence. Or bad mouth one or the other brand.
I think I know which ones right.
Thanks

Salifert is the best.
Many of the cheap test kits give a false positive reading of .25.
Oh, and by the way, discussing brands is never against the rules. Only posting competitor's websites links or names is.

I like the Instant Ocean test kits the best .
