just got my new axt1800 and here are my constructive comments.
that travel routers should

— run cool.
the axt1800 runs VERY hot, perhaps too hot.
as a result, might not be suitable for continuous use as a home router, unless i add ventilation.

— small size.
my ar750s-ext, is about a large as a travel router should be.
but with the axt1800, about the size of my raspberry pi4, with case, and ssd,

— small power supply size.
the provided power supply is way too large for the given output.

— lightweight.
the axt1800 is much heavier than ar750s-ext and then add weight for power supply.

so will make it difficult to travel with axt1800,
i think i will be forced to continue to use my old ar750s-ext.
