Keenstone Weighted Baseballs Softball Heavy Training Balls for Hitting, Batting and Pitching Training, 16 oz Baseball Practice Balls, PVC Shell, Iron Sand Filling

Nice thick rubber feel

Feels amazing. I toss the baseball to loosen up and then I start throwing the 16 oz. red weighted balls for about 30-40 minutes. Then I go back to the regular baseballs and the baseballs feel like wiffle balls. I’m loving this product.Note: I have a friend that has a similar product, they do deflate a little and get an awkward shape. His advice was when storing, keep them separate or on top of the other baseballs (or heavy item).

The girls really liked these and felt that these did make them swing through harder. Whether or not this computes to bigger hits in games... we will see in a few months. They did really seem to power the balls out there well with the pitching machine right after.Note.. We did NOT let them use their good bats with these just in case of internal damage that might adversely effect performance in the future.

So far so good, I've used these for my 10u and 16u team and they have held up so far. I have the more expensive weighted balls as well and these seem the same quality and weight. I would recommend these and will update if they go bad and how long it took.

Great product, would be better if there were different weight levels. But overall happy with the product

If you do not have a lot of space for your child to practice hitting or just dont feel like chasing balls, these are for you! We love them.

High school baseball so they got a work out and so far have survived two seasons

Balls came quick. Hood batting practice. Hit very hard only travel less than 50 ft. Have only hit once but seem durable. Time will tell. Happy so far
