Hey guys. I have Z5, ZCS, ZAIO, Z8 and ZFX purchased approximately 2 and a half years ago (give or take).
The stuff all smells fine - the Z5 showed some separation which went away when I shook it. But the ZCS has gotten "foggy." (Or was it always that way? I can't remember!)
I've heard these products have a three year shelf life - I've kept them under my sink and they haven't dealt with any severe temperature changes. But with that said, how on earth do I know when the product is no longer any good?
