1) charger arrived faulty - worked intermittently then stopped (this is only the charger - worked intermittently on other devices as well as the chromebook). unable to return/replace just the charger.2) sound is VERY quiet. needs earphones or a soundbar. speakers are underneath and downward facing, so if it sits on a mat or pad to keep it from slipping the sound is even quieter.3) this is NOT a fast processor, but I did not want a gaming machine. it is fine for what I want so I'm keeping it.
