My earlier review, which I can't seem to edit, said that the WiFi Antennae were not included.  In fact, they were, just very small.  They work well -- I can pick up a very weak signal from far away.The unit is bristling with ports.  You can plug lots of things into it.I've used it several times in cold night air, and it works fine.  Also, transported back and forth many times, still works fine.
