It's ok. I have a problem with it throwing an error saying that flash isn't installed or up to date. Get it on several computers randomly. If you go into the module and hit apply or save, without changing anything, it will fix it.
Which brings me to the heart of the issue... It uses flash. Wouldn't have bought it had I known. It's not very clearly stated.
I don't know that I would use this for a commercial site.
