I've been with CNS for 3 months now, using the San Diego location. My ratings is: Ease of Use 10 / Pricing 7 / Features 10 / Customer Service 10. I based this scoring considering CNS in contrast with another VPS provider I use and my home server as well.
I gave the maximum score for the customer service since they answered all my questions promptly (I had a couple of questions and requests, nothing wrong on their side, just things I wanted done or explained). Also last month when they had a power outage that caused some trouble they were very quick to fix it and inform the users about the issues and the progress towards solving them.
They are more expensive than other providers (I started at $30 / month for a 384 MB RAM), but given how stable the VPS was, and considering the low latency to my broker, I incrementally upgraded to 640 MB RAM, for which I pay $35 / month. I'll probably go for a 1 year contract soon, since they offer some discounts for that.
Also, another reason I’m using them is the use of Hyper-V technology, which gives you true Windows hosting (I use an EA that won’t run in a “Windows emulated on Linux” environment).
