i think this is good because its got a licence key and what bugs me is when I buy something for my mac sometimes I find out that other people are getting it for nothing from their mates or from forums but detoxmymac has a license key just for your own mac. i tried to use it on a mates mac and it couldn't be registered twice so I what I paid for is mine and nobody is gonna get the same thing for nothing from somewhere and so I feel good about that. when I first used detoxmmac it cleared loads of junk and my mac is much quicker now.
I reckon the firm which made it could make go a bit faster
