I put 'BAD' not because of the product, which has a good review generally, but rather that it creeps under the radar on 'free' ware sites, then whacks you for £45 if you want to use it properly. A quick 5 minute demo is hardly 'sharing' either. It might as well be in the same category as 'scam' ware when they use such underhand marketing methods.
I hate this crap form of selling.

This file, which I got from FREE Codecs, says it wants a serial number. Not very free, is it? Without one, it says it will enter "demo" mode. I don't know about you, but that doesn't sound like free to me. I think I'll pass on the spyware, thanks.
