It's not a rip off they come from Dingoo Digital China I order direct from the manufacturer I'm sure it's not a drop in quality or but don't know what it is at this point but I'm working with Dingoo Digital China and trying to work with Akemaul, Spiller, Joy Rider, and Haartex to see what if anything might be causing the freeze/lockups. At this point there is no way to point what it is.
