I completely agree with you.I belive heat is not a problem, as long you don't by the black one and paste.it directly in the strong sun. The cooling looks very good. I disassembled it very often, because I try to teach the device English or change the firmware. But this sucks a little because the whole system is protected and locked. Out of this point I would not recommend the device. The information based on openwrt is not wrong, but useless. The company changed a lot and not to the positive side. They should not do a commercial with openwrt when they look it like this. Nothing is open.
