I just received one as well for a friend. Purchased it from Shenzen Apexto on Alibaba.  Earnings estimates look pretty pretty close, 107 BTM after 21 hours.  Kind of expensive, and the firmware definitely needs to be updated as it has a couple bugs, but works ok.

No overclocking option, so someone with better skills than I in linux and cgminer will need to do an updated firmware to add that capability! (unless Bitmain offers it, which I doubt)
