"Great, Easy, Effective!"
Does exactly what it promises. Default settings are usually the right ones. I've now used this on my own computer (very intensive graphic design and live sound design setup) and on another system infected with much malware... CC still worked well.
Cons? They could bundle more registry handling tools... but that would be dangerous for novice users.
Use it!! But carefully, using defaults, unless you are adept at computer systems.
