The software suite is really helpful if you want to have better control of your file system (when deinstalling software, looking for duplicates, searching for big files.) or the memory management (memory cleaner, selection from services at startup.). I am a really happy Maccleaner Pro customer. Great software and a very kind and helpful support.
Personally my favourite feature and why I purchased the software originally was for the application uninstaller as I found it very hard to uninstall old applications before I had the software and there would often be 'leftovers' from old apps which MacCleaner Pro can also detect and delete. The software is very good and can highly recommend as it works well and has many features including simple ways to delete old files and free up disk space on your Mac as well as increase performance. (Not all companies would do this and lots would make you buy the newer version instead of upgrading users from the old version for free) They were very helpful and directed me to an updated version 2 that was included for free with my original purchase of the old version. When I emailed into support with my issue I was amazed when I got a reply within 2 minutes of emailing them originally!! I had an issue with the older version of the MacCleaner Pro software. Support replied to my email in 2 minutes!
