When we first received everything ran great, the first day my son actually went to use the computer the whole system seemed to crash. I emailed customer service and seems the Windows 10 file had somehow corrupted. They sent me a file with the Windows10 so we tried installing ourselves but it still wouldnt work. I emailed again, and they immediately sent me a new hard drive with the OS preloaded. Everything seems to be running great now, and my son is enjoying his new christmas gift! Customer Service was very prompt and responding and helping resolve the issues I was having. I would definitely buy from them again.
