I just purchased it today and will integrate our site to their platform. I will let you know how it goes.
Yes, we use it, you check our site: www.1cv.eu
Instead of building your own job board and having to go out and conduct sales and marketing to get employers to post to your site you should look into a branded niche job board to your site with relevant jobs that your audience would enjoy.
A great full service job board option is JobThread, they host the jobs, conduct sales and marketing, brand the job board to your site and much more. Let me know if you have any questions!
