The free version doesn't have as many features as the paid version, so there are a few alerts and prompts that are repeated or not necessary. Some cleaning actions would need to be manually reviewed so as not to remove important files. Every once in a while, an update would change something in the interface that was odd. Generally speaking, it works well, but these petty annoyances pop up every now and then. Review collected by and hosted on G2.com.
