I'd say their support has been marvellous. As for stability it also good, near 99%. Sometimes I had troubles with network due packet loss and sometimes was slow page loading, but than I figured out it was my problem, because I've overloaded database with wrong tweaks. The best part of their service for me is included features. I can get all needed software in a click, so it is easy. Yeah, I know that other hosts are also provide that, but before I've never met such big variety of apps included, for me it is good, because I love to experiment with different soft in search of best fit for my demands. Overall I suggest you to give a personal try to Kvchosting if you need reliability of high level hosting service.

One of the cheapest and reliable company I have ever found. Good backend support team which is always there to help you. Website loading speed is also good. Almost completed 1 year and till now very satisfied with them . 

It's really perfect for all developers.

iFihost.com is best web hosting company. i'am use their xen vps hosting. it's really faster and best.

Great host, found them on Twitter! Not as cheap as some services like HostGator or GoDaddy, but you get what you pay for. Speed and uptime are both great, haven't had any issues so far. Highly recommended! Wish they had live chat support, but email support is good and the turnaround time is still leagues ahead of HostGator.
