Fast, free....what's not to like

Needed a simple app for quicky cleaning browser caches and junk. That's what it does, and some more.

Great but incomplete

I can find duplicate photos in photos app even after I run the duplicates program specifically on the photos.

Otherwise I am saved a bunch of space.

I also love the quickview option to see how much ram and cpu I have left

OK so far

I've had the app for a couple of months and no problems so far. No crashes and easy to use, but the power cleaner is slow.
