Naw, that sounds about right. The review I read rated it as 2.5 alt country bands, but I saw a picture of the guy, and he was way scrawny.
With my electric bass, I once checked it on a flight from Charleston, SC -> Newark, NJ -> Washington, DC. It was maybe 50-60F in Charleston, snowing in NJ and probably in the 40's in DC. Also, keep in mind that it was in the cargo compartment. I showed up at my rehearsal in DC and it was perfectly in tune.
