(A) Never heard of 'em -- That said, their website seems to have gone live just last month and their FB page has 7 likes, so I'd imagine few have at this point. (EDIT) Their FB page says they just had their first order 15 days ago (/EDIT)
(B) Doesn't mention the brand of cable and I assume they're not rolling their own, but I kinda like to stay with "tried and true" stuff if I can help it.
(C) Doesn't use "familiar" connectors. They look like the ones Bespeco uses - which I have no particular experience with if that's the case.
Nothing illegal there, but I'd be looking for a more "known quantity" (lack of a better term).
