After following a forum members lead I am shocked at how efficient this new miner is

This new Bitcoin miner has the BM1373 chip which is more efficient than the BM1370.

I am so tempted to add this to my collection right now, but since no thread about Bitfortun miner on the forum I need to ask how the performance truly is and what the experience have been so far.
Anyone running Bitfortun Asic miners on the forum?
I guess this is the latest most efficient chip right now? Or something new is out? Please kindly drop review if anyone has this miner or this brand running.
