Initially this looked nearly brand new.  It had a couple tiny dings on the edges but nothing noticeable.  It worked great for a few weeks, and then the keyboard started having issues.  The keys would stick and make multiple of each letter being typed.  That issue makes writing reports a lengthy process.  We used compressed air and went through the usual trouble shooting suggestions recommendations from Apple.  The problem was not resolved.  Then the battery started dying unusually fast.  We messaged the seller, only to be told we missed our return/repair date by 1 day.  They didn't offer any suggestions or support.  We pointed out that it was one day after the return/repair deadline and that we had already taken it to the Apple store for maintenance at our own expense, and had hoped the issues would be resolved.  Unfortunately, we have to take it in to the Apple store and have the battery and the top case replaced.  Frustrating experience and definitely don't feel confident in buying from them again.
