I was afraid you were gonna say that  :/

Globalscale's somewhat infamous for heat issues with the Guruplug ; the 
mirabox is supposed
to not have the issue, and I don't immediately see any reports of it, 
but it wouldn't totally
surprise me.   The boxes are fairly hot to the touch (It won't burn your 
finger but it definitely
gets uncomfortable), and that's in a basement where the ambient temp 
probably never goes
above 75f.

Another clue in the heat direction might be that with the rain the last 
few days things seem
at least a bit better, though it's probably too early to draw 
conclusions.  First box's been up
for 2 days 10 hours now, and the with this oops above 18 hours.

Thanks for looking again.
