Hahaha !

I guess you have not seen the failed ones yet (Iceriver KS units), over time the chips die or the units have the thermal paste off-center under the heat sink on the hash boards from the factory causing them to run hot !

They also have bad customer support (Iceriver) when the customer needs assistance to have units replaced etc, seen many complaints about it.

Iceriver EU ....   is a scam and not their official outlet for Iceriver.
