We had a number of players use the Mayhem bat this year during the summer. We even had it a feew weeks before it hit the market.
In general it is a very nice bat. It is well balanced, has above average pop and it seems to have a pretty big sweet spot.
By comparison I would say that it is an improvement over the old Miken M-Pulse which it essentially replaced.
I hope that helps.
