It varies - some hitters feel a difference after using it once. For others, it takes a few days. Either way, you will notice a difference in your swing after a week of consistent use.
What happens if it breaks?
If your Thick Grip Bat breaks within 30 days of its arrival from normal use due to a defect, you get a one-time replacement free and we merely ask that you get the bat back to us so we can inspect the defects and improve our manufacturing if need be.
Does the bat come with anything else?
Yes, along with the Thick Grip Bat, your order includes 8 hitting drills you can use to accelerate the results of your training.
