I have been using this host for several years now with over 100 sites hosted here so far without any issues at all! They're also very helpful when it comes to advice or troubleshooting problems that arise along your way as well - their customer care department has helped me out more than once already (and they reply within just minutes!).
There's nothing about them really from my point-of view but maybe pricing could be lower? If you want reliability then go no further because there isn't anything else better around if compared against price/reliability ratio :) Support via chat was excellent too even though sometimes we might get disconnected during conversation due to high load traffic etc., however overall experience wasn´t bad nor good either :). The best thing i like the least would probably be speed & stability while browsing certain websites such us Google Maps where other hosts usually work.
