What does the software or service do well? For the money, it is a great service. It is not for anyone being serious about their hosting, especially if it should be used for business or for a large number of visitors.
What does the software or service not do well? It's really worth the extra money just for that!
What do you wish you had known about the software or service before using? If you are even considering switching to a new hosting provider... switch over to Hostwinds without looking back. Besides, their support is really worth it for me. It happened so they helped with things like Htacess files, and almost any web admin question I had.
