I ordered more than one. 
Basically I know that the design works since I already build one reader but now I need to test if it works every time so I'm gonna build four more readers and test them over a longer period.
So the release is still longer than days away, hopefully just weeks, worst case scenario months but not years. 
After four years in development it is time for a V1.0 release and all that is missing for that right now is a video about the build/soldering process and the finished and tested pcb. 8)
