I searched a bit to find that this miner is being sold on Ali Express and the brand making it was Abdo which says nothing to me,maybe they are good ASIC manufacturers but they can't go and sell their ASIC at a huge price that I saw at Ali Express which was 4000 dollars as they are not a known brand.

If I assume they are a good brand,having that optimized mode at 2 Ghsh at only 850 watt from the wall sounds like a nice miner to mine LTC+DOGE.
