can anyone tell me a little more about this what can you do is it any good what does it cost etc is it worth using

Well what do you want to know about it. It allows you to register domains, setup costs initially are $250 or $500 depending on what type of implementation that you want. It is a great system, and they have very good support. The API is easy to integrate with your site, and it is a standard $10 per domain registration. The 250 or 500 fee upfront covers 25 or 50 domain registrations depending on package you opt for. You can manage your domain from any opensrs reseller site, which is nice as well.
