SEEMS GOOD SO FAR... I won't say much yet until I'm more certain - - may even subtract a star or two if necessary - - but right now I'm fairly impressed. Seems to do a fine job in cleaning up the various caches  and it does make a difference in speed & performance. But I've tried other apps that later proved disappointing. If that happens  I'll definitely change my opinion to let you know. For now  I'd strongly recommend this app.
