I didn’t see the UL safety rating on the pics. R Amazon electronics not rated safe by USA Underwriters Laboratory _ does this not meet UL standards for safe use in USA?
It’s ETL tester/listed to UL standards. Intertek (Edison Testing Laboratories) is a NRTL.

On the mother it’s going for $16.72 . Picked one up on woot.
I just received mine and the user manual says : “It is normal for the power strip to heat up to 170.6°F (77°C) during use.” That sounds dangerous.
I’m guessing that is referring to the USB charger part of it? Sometimes those chargers get pretty hot. Still seems pretty high though.
I bought one and have used it for about a week or less and it’s already broken 
I tried all the ports including adding a plug (was charging my iPhone). The blue button is lit. I even reset it using the little pin hole.
