"The website has a wealth of information and makes it easy to choose the software that would serve my needs. I was looking to do a major cleanup on my two older PC's and hopefully improve their performance. I'd used Auslogics Disk Defrag in the past and was very impressed with the speed and thoroughness, so choosing Auslogics for my other maintenance needs was a no-brainer for me. I bought BoostSpeed 5 and found it to be a perfect match for my two systems in that it cleans and speeds up without causing any problems or errors like I heard other similar software may. Overall, it's a well-made piece of software. "
