I’m not sure how to rate this.  On one hand it arrived quickly, was easy to set up, and did what it was supposed to do(*).  BUT(*).... it crashed every 10 minutes which made it impossible to have serious meetings efficiently get work done.  Tech support was reasonably attentive. However, in the process of creating a bootable USB everything failed.  Support suggested taking drives out and checking piece by piece, but I don’t have the time, energy, or confidence in long term success to do so.  So I’m sending back. 😕
