Hello. I have been running 10 of these in a hub and one in the addition USB port on an old laptop. They are functioning fine. No DOAs however I do have to reset everything every once and awhile as usually 2 stop hashing. Once I reset they are good for awhile.
They are getting hot to the touch. I moved them to a window sill where its cooler and that has helped.
I ordered more and a bigger hub. I am mining dogecoin.
the real test is what's the longevity of those things. will they break in a month? 3 months? 6 months? and what's the warranty policy? is the manufacturer going to be in business or will they go out of business and change their name to release yet another miner? (so you have nowhere to turn to for warranty)
