I just took a quick look and frankly I'm not impressed....

It's not very comprehensive, it contains some very specific vulnerability tests that are also fairly obscure. You get the test number not it's text so you have to click them all to see what they address. If you ask it to run all tests it points out that this is very innefficient.... blah blah blah.... You can't simply put a target in, you have to change the config, then when you do it asks you to save it. When you close and reopen the old config is gone...

I'll stick with Nessus thanks....
