After a huge fug-up by UPD/USPS and a call to EforCity, I finally got 2 converters, one will be "return to sender" and one is now happily providing me a high def picture from my Roku2 and Sony.
Only issue is that the maker has installed a one point twenty-one jiggawatts laser instead of a simple "on" LED.
The light actually fills my entire room! Need to find a piece of black electrical tape to cover that sucker up.
The shipping mess was pretty bad, 12 days to ship. EforCity sent another one Saturday regular mail and both arrived today (Monday).
Great customer service, I think I will use them for other stuff.
