Expired red sea kit. Is it usable?

So my lfs cut me a deal on this 3 in one test kit by red sea. However it's a bit expired. Is any of part of it is still usable. If even one part is done after exp date then I'll be happy I only paid 15 for it

Do you know what your parameters are already or have another test kit to compare results with? Since you already bought it, maybe run each test and see how accurate it is

I can confirm the alk test doesnt work

My 3 month expired red sea kits read roughly the same as my fresh stuff I bought to replace it. As close as my bad eyes can make the kits accurate that is.
