Never knew that tool. Their Video need to be improved because the product seem nice but they really do not sell it well :P

Um, and if you like that, try the free enhanced version from Sauce Labs called Sauce IDE which records videos of your tests running in cloud space. Makes troubleshooting way easier. (I cofounded Sauce with @hugs)
