I finally got my b29 I ordered and I must say it is the nicest asic miner I've seen. It is smaller then the antminers and a lot quieter too. The power supply is also very nice because they give you a little bit extra cable length unlike bitmain's power supplies. The GUI is also very nice and allows for automatic firmware updating along with a built in tuning feature. I wish they allowed for some manual overclocks but they said they will be adding new features to their software in the near future.
