Satisfied with Device
I am satisfied with my purchase, works fine and is small enough to take anywhere (OTG).  The only comment I have is, the battery door is a little difficult to open and a little flimsy, I fear that if I open and close it a few too many times it might break.  Just hope the battery life fairly long to reduce the need to open and close the door.  The device operates as advertised.  There are no operating instructions with the device but it is easy enough to figure out how it works.  All in all I am satisfied with my purchase.  The only reason I didn't give this device a five star rating was the door.  If I would have been able to give it a 4 and 1/2 star rating I would have.  I would recommend to the manufacturer if possible, there is room on the source side to add an SD card slot.  This would eliminate the need, for many, to purchase the SD to USB adapter.
