Old test kits

[puntific]

I have a collection of test kits by API which are about 2-3 years old. Which, if any, would you trust?

pH
Nitrate
Nitrite
Ammonia
gH/kH

Thanks,

Old and in date or 2-3 years out of date!?

I was curious so I just used an old Ammonia kit and a new one and got identical readings from tap. So that one might be ok..

Well, it looks like they have a date on them of 2008. Thoughts?

If it were me I'd throw them out. It's not like test kits cost a ton of money. I tend to be safe rather then sorry.
