I installed it and used it for about 10 minutes before uninstalling it. I never tried the beta so I wasn't familiar with it. I must say that it doesn't get any more simple than this. I think simple is good, but personally would like a few more configuration options. I ran a quick scan and it detected a Creative exe file in my SysWOW64 folder as being a dialer.
I didn't see anywhere where it would give me the choice to ignore it, it only said that I could restore the file if I wanted after reboot. The file was digitally signed by Creative and matched the date last time accessed when I installed my sound drivers. I just didn't get a good feel from the product personally, so I am back with MSE.
