Scammish. Doesn't record live streaming videos. Gives you a hit, and then takes you to a page where it wants you to pay $20 or more to download the Ultimate version which apparently gives you the capability. I have no problem paying but be upfront about this being a paid app from the start.

A short trial of the software (a few days to a week) would be good to let potential customers test out the basic features to determine if this is the extension they want to use and spend their money on.
