I don’t think I’ve ever written a review before, but I feel it’s warranted in this case. On day two three of the keys stopped working unless you pressed them ungodly hard. I emailed them and they said to send the computer back. I couldn’t as I was using it for work, so I just fixed it myself with the help of YouTube. Two months later, the third-party charger they sent with it stopped working so I asked for a new one. They said to send my computer back. I asked why and got no response. Now, my ninety-day warranty has ended and another charger has bitten the dust and the actual port is burnt. I’m not sure they actually read emails as the only thing they’ve ever told me was a copy-and-pasted “send it back.” Not once did I get any actual communication or conversation, even though I tried to initiate it many times. I realize it’s refurbished, but I think you should get working keys in the deal. The Mac itself, when operable, is good. No software problems. But without power it’s a nice silver placemat.
