THEY ARE NOT EVEN LOOKING AT THESE THINGSUpdate 11/20/14- Dropping rating to 1 star for consistently crappy quality.  Deserves less than that.Missing keys, dirty, units still provisioned for previous owners' enterprise systems... CHEAP, SLOW CHARGERSNot so much 'refurbished' as dusted off and thrown in a box.  They are not powering them on and I doubt that they are even being opened.Ordered ten of these units and here's what I got:  Three have damage to the key reveals (little plastic trim that sits between the keys on the keyboard.  One unit in the order arrived with a missing key.  Another one is still provisioned under another school district which makes it unusable for me.Also something to note: In an order of ten units, only two included OEM AC adapters, the remainder came boxed with cheap replacement tablet-style chargers that are painfully slow to charge the devices.
