Kid is a catcher and has used this for 3 months and has improved his arm strength. Uses this every night before bed using all 3 bands. I have seen the results in practice already.
Bottom Line: I would recommend to a friend
Great product! My 12 year old has been using it almost every day and it has definitely increased his arm strength and pitching velocity., Well made!,
Pros: Well made!
Still too soon to tell
