I ordered two of these bats as birthday gifts. I was concerned about the adjust-a-hit technology holding up after repeated swings and adjustments, but a positive review on a different site led me to try this bat. I checked both bats when the arrived to make sure they adjusted without issue. They did. Fast forward a couple of weeks to their first use. One bat adjusted correctly, but there is still some concern about it holding up over time. This bat stayed in the adjusted position after multiple times batting that first day. The second bat immediately broke upon the first swing. It's locking capability does not hold up when the bat is swung. I will be returning this bat.
