yomega ooch smoov and kerrari?

has anybody played either of these?

I have played the ooch smoov. It was very surprisingly good for Yomega and i own several of their yo yos. It became unresponsive fairly soon and grinds really well. Has a long spin time too. Only problem is that it breaks strings a lot because of the bead blast. So the Ooch smoov was surprising to me and my neighbor.
