I have been using Recruit So Simple for over 3 years now. They consistently provide a good service and their product has proved to be reliable, with only the odd hiccup here and there. It's lightening fast to use, including parsing CVs, searching etc and I especially like the way I can sync my calendar to Outlook and Gmail. Managing my consultant's tasks it also quite intuitive and makes my life easier. Having tried most of the products on the market, they often draw you in with false promises. You can't go wrong in choosing RSS, they are definitely the market leader. Long may it continue.
