Well, what a coincidence: mere minutes after reading the review complaining about the sharp edges of the Jr.'s casework (a valid beef in my view, but not a deal-breaker), into my inbox comes an email announcing the availability of cases for it.
I got the same email. My review had no bearing on the making of cases (which should have taken months), but the wording of the copy is obvious: they are admitting design error:
"AK Jr users! Looking to soften some of the edges of the AK Jr and give it some protection from everyday use? The AK Jr Case are available now at the Astell&Kern e-store! "
