just because the source doesn't come from this particular site doesn't mean it can't be trusted nor verified. as for gorilla gear, I've only heard from one person who has actually used it, a guy I trust, he was satisfied but he uses various stuff depending on where he is what he is doing. he also home brews sometimes and only used them once. some sources have been known to vary in quality from batch to batch so maybe try to get a few more reviews. or if you know anything about gear yourself be a bit of guinnea pig and see what's up. if you don't, wait till you have more info at least.
