Agreed, 18 gauge isn't enough & the price is too high. These reasons alone are enough not to buy one, but the workmanship, quality & history of Bitmain brand PSU's (S4) are even more reason to avoid these. Bitmain have already lost one of their own mining farms to fire, it's no surprise why looking at those pictures, you'd think they had learned their lesson.....

As far as PSU's go, you can't risk compromise: quality parts & workmanship win every time, something these don't have. It's just not worth the risk.
