    Extremely basic cleaning tool, with a mediocre scanning algorithm. I compared it with some other cleaning tools, others found 60-90gb of junk total this one only found 4gb worth of junk. In addition not everything is properly translated into English, the scanning results were all in Chinese despite me selecting the English language.

    There are better Open Source alternatives with the bonus of not being from China either.
