I had a total of 3 times delivery to computer. The first time, he turned off unfounded. Well, it can happen. But what makes the dealer? He sends me again to a computer to have repaired without him, stating that they could find no error! I was very upset. Again the computer over (a really big box, every time I had to drive to the post office). Finally it was said that the power supply is broken. Overall, six weeks after the order finally works the computer, but the dealer has given me the shipping cost is not refundable, even though he had promised me and I've often pointed out. He simply ignored my emails. Conclusion: Stay away from this dealer!
