I've been a customer for about 2 months. And I have been very happy. I was with my last host almost 10 years, so it took quite a bit for me to change.
They have had some problems very recently, but I beleive it's been because of several factors coming together at once, and not any one shortcoming. Their record seems to be very good prior to this recent Hickup.
The few problems I have had have been resolved fairly quickly (esp when you mark the issue "site outage"). Not as quick as picking up the phone and getting someone on the line immediatly, but within a few hours (which is good enough for my sites).
If I needed 99.99% uptime or my business was going to be in jeopardy, I wouldn't suggest them, or any cheap host.
For the cost I have found them very feature risk, with very few.. kinks.
