I have really liked the product for a long time. In addition to a GREAT product what impresses me is the customer service. I recently was having a difficult time moving a website that had a pretty large file size (3.8GB) from a live sub-domain development server to the root server for the go live presentation.
Their support was extremely helpful, went beyond the call of duty. The web site went live without a hitch. These folks are the BEST!
