It seems to work good, it just looks awful fishy. It looks too "cool", like the scam programs, but I can't tell if it is or not.
It is crap in my opinion. Better off opening up task manager and killing anything you don't need running. Everything else it does can be done by windows.
For a while I used it and it didn't seem to do much but take up RAM. Most of the tools are useless and there are better versions of the good tools elsewhere. Just pass on it.
