The only thing I don't like is online registration (but, you don't have to do it for 30 days, so, if you don't like the plug, after 30 days you can simply delete it) and the fact that one can use an e-mail only once to register the plug (I did it first on my laptop and after that when I came to my studio I found out that the serial that I had was useless, then I had to go online and found out that I can't use the same e-mail).
OTOH, the plug is really interesting and well worth trying, imo (again, you have 30 days to see if you want to keep it).
Cheers,
