I ordered 2 from them a couple weeks ago. The order went 4 days without any movement, so I called them up and asked them to either refund my order or expedite shipping. They overnighted them to me. Was pleasantly surprised. I also received the 16 Guage cables, which was nice - as the other 2 x s4’s I already had, did not come with them. Saved me a trip to the hardware store. 1 of the units booted fine, the 2nd one - did not. Was DOA, but rather than try for the RMA route, I busted it open, as I could not access the reset pin on the display screen. The LCD was slightly off alignment. I disconnected the LCD screen from the front panel and disconnected all cables to the boards and PSU, then reattached them. Also removed the SD card and reinserted it (did not have to flash), turned it on, and low and behold it was working - although the display seems broken as only half the characters are visible - it’s hashing away at 2 th.
