4.99999 stars. Build quality of the machine was neat and flawless and it arrived on time. Would definitely get future rigs from them. I also had a minor setup issue to troubleshoot, and the articles on the website were very helpful, saving an unneccessary call. My only minor issue is that with a 15-20 day delivery time, you're not given much by way of updates, and then when they eventually start, about 3 weeks after ordering, you get all the updates on a single day. Perhaps an ETA date on the order tracker would be better, so you know when to start looking. All we get is a weekly e-mail saying you've prgressed on the queue. Patience runs very thin when you're excited about a new rig.
