Pros: My 9 year old son loves this bat. It has good pop and is nicely balanced. Last night he had a double up the middle and a triple off the fence to the opposite field. Make sure your hitter is close enough to the plate, the sweet spot seems to be closer to the handle than the end. I would guess that his teammates will be lining up soon to use it!
Cons: I cannot comment on the durability, as he has only had if for a few weeks. It does vibrate some, but no more than any other model.
