"One of the few utilities which isn't freeware"
It makes a lot of necessary work easier to accomplish, but that's what it's supposed to do. It does them very well and I'm pretty fussy. It also is significantly superior to Glary Utilities. If that weren't the case I would be using it.
I might add a tool or two but it's still worth more than its price.
