Bat Weight - Increase Bat Speed and Power - Easy to Attach - Compatible with Wood/Metal Bats - Best Baseball Bat Weight for Training - Perfect Bat Weights for Baseball Youth

Just received today and was skeptical after reading a review that it didn’t fit the Marucci cat 8 or 9… I purchased this for my 7 year old son who is swinging the Cat X and it fit flawlessly and upon its first couple swings is giving the desired feedback.

My daughter used it and loves it she loves that she still gets to use her bat instead of a training bat. She loved that it was easy to use. It’s puts the weight in the right spot for what she needs to work on and she can control that. She has a Camwood and instantly said she prefers the hitting knob over the Camwood.

Spring never functioned and now have to go through annoying return process. Awful

Lasted for a little over a month before the spring mechanism failed. Also, knob would occasionally come off the bat when was working. There needs to be more of a lip to hold the knob on the handle better. Will not buy again.

My daughter has been using this for the last 2 weeks during BP warmups, and when she’s on deck. I notice a big difference in her swing. She definitely has quicker hands. Very easy to pop on and off. This is a must buy.

My 13 and 10 yr old like it. Haven’t used it enough to see if it truly helps, but I they definitely get feedback while swinging it. The knob even rubs wrong against my 13 yr olds wrist when he doesn’t swing it well. Which is a good reminder and motivation for him to correct it. Only complaint is that it doesn’t fit on the knob of our Marucci cat 9 (31”) or cat 8 (29”). Works perfectly on our Easton ghost x and barleys squeezes onto an older Mizuno 28”.

Bought for kids and they love the feel and how “light” their bat feels after.

Love this product but mine was defective because after a couple of months the edge of the lip that holds the bat in place broke and could no longer hold it in the weight. I had to order a replacement. I didn't do anything to abuse it that would cause the issue
