Purchased a computer from them for my business for my interns to use. ( 2008 Macbook 13 inch. with 1 gig of ram in it. ). I only needed the computer for internet browsing, emails, Microsoft Word, and other small tasks. I was told by the specialist that the computer would be fine just the way it is for what I was using it for. No upgrades were needed at the time. a week after I got my computer the battery blew out. It would die at 67% everytime. sometimes it would make it to 45% ( if I was lucky ). Also when I went to go watch a video, the whole screen would go white, not acceptable. They took it back, changed the battery and fixed it. then the battery went out again, and again. and a bunch of other problems. fast forward and I'm 2 months past my warranty, but i haven't been able to use my computer since day 1 and they're giving me a hard time about trying to get my money back. How can my warranty be expired if the computer never worked in the first place. So here I am, another crappy battery and my computer has a stockpile of other problems, oh and my battery dies at 70% now, an all-time record. They have blocked my phone number after I threatened to send them to small claims court, and I can't sent them email either, you try and use your small business to support other small businesses but sometimes it doesn't work out. the owner Mr. Wegener is a class-A scammer, He'll give you the run around and I think he hated me because I knew what I was talking about when he tried to play me countless times, and at the same time, Ive gotten them countless sales from family, friends, and other companies looking to save money on "refurbished" macs. I'm honestly not mad over the computer or anything, its only $250 that I spent, the problem is, now I have to find another store to buy macs from and My company is growing and you can't trust these guys. Oh well...
