I had never heard of them until just now lol
I looked them up though. Newegg doesn't even carry them except through a marketplace seller. They appear to be an OEM-type supplier (like SK-Hynix) with the majority of their sales through venders, like you're saying, and appear to only carry the very most basic design and speeds. Since they're rarely sold retail, there's no RMA data for them.
Comparing the price of EDGE to G.Skill from newegg marketplace, cdw, amazon, provantage, etc., it seems EDGE costs about 50% more for the exact same thing, with worse latency.
