I used it for a while and never really decided if I liked it or not. It's both more advanced than dopus mag in some ways and behind in others, but with a Windows twist. I will say I prefer it to dopus 4.x (although that's not saying a lot), but vs dopus mag I think I prefer magellin (although maybe because I know it better).
At the end of the day Explorer does a decent enough job and has enough features that it's unnecessary for me, so never bothered re-installing it again.
