FWIW, these appear to be the same product, re-labeled by two different companies... unless it's just a coincidence that these devices have the same back panel with three RJ-45 plus DC-in and blue curved housing?
My guess is that it's made somewhere in Taiwan or mainland china and might be available at a much lower cost. :)
