MFOG is not quite as strong as Go++". DM (7-Dan), Review in American Go E-journal

"Based on playing 4games with Go++ I'd say it's strength with 6.5 pt komi can be bounded btwn 9k and 6K. Which IMHO is truely amazing for Go playing software." DK, USA.
"First let me say I think Go++ is a kick-ass program. As a newbie I pretty much learned how to play go by playing even games against MFOG10, and I VERY MUCH disagree with those who discouarge other newbies from playing against computer programs; because 1) they are fun; 2) they are always ready; 3) they are stronger than any newbie and make the newbie very aware of his cutting points, killable groups, that kind of thing." BH, USA.
"Go++ is not only the strongest-playing program that is available to the public, it is the least expensive of the strong programs." NW, Review in the British Go Journal.
"I think go4pp it's better than MFGO11." SV, Romania.
