"One of the best and lightest Optimizer there"
Good UI,Light on computer,Optimizes well,Tons of features.
Pricey,Takes time in scanning.
Well if you're looking for a good system optimizer and are willing to
spend money then it is the best option for you.B'coz it can
scan,repair,optimize,undelete and could do much more.It doesn't slow your system and performs well too.
