They are great hosts with great prices. The only problems I find is as follows:

1) They don't answer their phones.

2) They seem to make major updates like on their email and DNS servers and they don't let their client's know in advance. A simple email explaining their cause and possible effects would be extremely helpful in having webmasters ready to go if their site is down or needs to be adjusted based on updates or new settings. You finding out from clients that your website is down and not by the host is troubling.

3) They don't answer their phones.
