We've used it in the past, and will in the future - BUT this is not rigorous usability testing of the sort that you'll get in the lab. They're self-selected and they don't do well with loosely defined objectives (even though they tend to be North American native English speakers). If you have access to a Mac and can recruit your own volunteers (college campus, etc), I'd recommend getting Silverback - http://silverbackapp.com/ http://silverbackapp.com/ . Not only do you get the screen capture, you also get to see frustration/delight on users' faces. Plus, it's cheaper if you plan on doing four or more tests.
