Heard of it mentioned briefly before and did a bit of diggin some rate it highly but one persoin said this and it sent chills down my back, here is what he said quote:
"The program is awesome and sped up my computer 10 fold. The tools fixed a myriad of problems on my drive and I was very grateful. Then came the questionaire... it stated that i had been using the tool for a while and asked if i would like to take a small survey. I said why not because I'm gonna buy the software anyways. I decided to go ahead and click the ok button and thats when all hell broke loose. The site began to load but then it froze... I waited for a bit, but nothing happened. So I went ahead and closed the browser. To my dismay... my desktop picture was gone. I went to investigate and found none of my pictures were in my drive! So I immediately began checking what else might have disappeared... the results weren't too good... my music was wiped... my launch icons were all gone... my word documents were gone... basically anyhting that was a personal file or document had been wiped. I am stunned but now I'm gonna have to go to a pro to recover all of the lost data. Buy the program off the bat but DON'T TAKE THE SURVEY!!!!!"
Scarey mate, here is the link to the site that reviewed it and check out the section marked user reviews, i wouldn't trust it by the sounds of it!
