Any group of posters devoted to one product, be it Supratek, or something else entirely, is a scewed sample.
I imagine that only those with a positive experience will bother to post here.
If I didn't like a certain component, I would never post in respective thread, just simply move onto something else.
Another consideration- if one doesn't like component, this means one needs to sell it. Posting ones negative impressions about it would not increase it's market value, would it?
Does it make Supratek an inferior product?- absolutely not.
Is Supratek beyond criticism?- possibly not.
