Yeah- it's not as though they can save an already oxidized beer. Thanks for the awesome explanation btw.
Until recently I had been using the oxy scavengers but I doubt I'll spend any more money on them in the future.
I'll try a side by side comparison when I bottle my imperial stout. It will be a while before I notice anything I am sure.
Maybe it would be worth trying this with an IPA to see if they really absorb hop flavor/ aromas as well.
