Absolutely avoid this seller...if you have a problem in the future he will treat you like dirt.<br />We bought an iPad a year 1/2 ago, and not only he did not include the serial number on the invoice but he continues refusing after numerous requests ( by the way, he simply does not reply after second request). Apple requires the serial number on the invoice otherwise will not help you...which means the iPad we purchased is absolutely worthless.

My dad builds computers. He gave me a newly built computer 6 months ago and the hard drive went out today. I lost 6 months worth of pictures and work documents.<br /><br />The hard drive is fried.

This is actually my second order of these. The first order did fine for quite a while but then I got a lightning strike that blew out many of my devices. These things are amazing I have four of them in my house and I always have five bars on my phone or ethernet device. They easily connect to each other the software is good. The only problem is when the other one was failing it was very difficult to figure out that I needed to replace it.finally after quite a few hours of troubleshooting I just decided to replace the device and everything has been good ever since then.
