I've only recently tried Cloud System Booster but there are a couple of issues which I'd like to query:
1) The price is $19.98 for just 1 PC for 1 year. In this day and age most computer savvy people own several PCs and may be a Mac too. Glarysoft's utilities are equally good if not better and they are almost completely free
2) I've got several PC clean up utilities including Advanced System Care, Ashampoo WinOptimizer, CCleaner and Glarysoft. However even after I've run all those other utilities Cloud System Booster claims it's found tons of other data debris? So how much of the what Cloud System Booster claims to have found are really just false postives?
3) Despite how much Cloud System claims to have cleaned off the PC, I can't honestly say I notice much if any difference?
