F10sc

I was just at a reptile show and they had F10SC and I noticed on the bottle it had an expire date. (it was still good they weren't selling out of date) Does any one use it and if so do you buy new every couple years or is it still ok after the expire date? I want to get some and was just curious about that. Thoughts, opinions?

As soon as you pop the top on it, it starts to go bad.
Ineffective is actually a better term.
Kitedemon would be on of the best ones on this, search for some of his old F10 posts.
