Guys, who installed MacKeeper utilities for themselves? Is it worth it?

Hello everybody! I didn’t bet and I don’t intend to. At first, I confess, there was such reasoning that it would help me and my laptop would work faster. But everything has changed since I came across an honest review mackeeper (https://macflypro.com/reviews/mackeeper-review.html), who spoke in detail about everything related to the work of those 17 utilities that are presented in this application. In fact, many of them are not needed in principle, and the other 5 can be used easily and for free. Then the question arises, what to pay money for?
