I placed an order for a refurbished 27" i5 on August 1st. The unit arrived that Friday and immediately out of the box it would not stay on. The screen would just go black every 15-20 minutes while I was working on it. So, that one was boxed up and sent back on Monday the 9th and my second refurbished i5 arrived this past Friday. I took it out of the box and got it all set up after work that night and noticed on the lower left side of the display that it had about a 1/4" crack right through the screen. I was beyond frustrated that I would have to send another unit back, but even more so that I would be without a computer for another work week. So, yesterday morning I placed the call to Apple Care and told them I would need to send this unit back as well because of the cracked screen. The agent apologized that I have had to go thru all of this trouble and said I want you to talk to my supervisor about this. He got on the phone and I told him the issues with the two units and he asked me if I had a Apple store near me, which I do. He took my phone number and said to give him about 15 minutes and he'd call me back. When he called back, he told me to box up the second defective unit and take it over to the Apple Store and they would be giving me one of the brand new i5's for all my troubles! I couldn't believe it. I boxed the unit up, asked for the manager when I arrived, he apologized for all my troubles and handed me the brand new i5 iMac after doing a little paperwork. I thought this was incredible customer service and just wanted to share a fantastic experience with Apple. Oh....the new i5 is perfect!!
