Pytanie Have yet to get any useful results

I have downloaded Catzilla and run several full tests. I never get anything under Recommendations > Hardware. It's either "you need to perform a full test," or, immediately after performing a full test, "check back."

I haven't gotten any value out of this utility so far and am kind of wondering if it's a big scam.

Same here. I've seen this question lots of times in the forum and the Devs always avoid it. Let me know if you work out how to fix it!
