PRECISION IMPACTWeighted Baseballs: Weighted Baseball Set for Throwing/Pitching Training (Includes Durable Drawstring Bag)

This greatly advanced my training and ability for pitching.

Updated Review: Within a couple hours of contacting Precision Impact via email with my issue (original review below) they got back to me. On the Labor Day holiday no less. Precision Impact was all over rectifying the problem and I already have a replacement in hand less than 3 full days later. I hadn't originally noticed their box marking claiming "100% Satisfaction Guaranteed" but they surely lived up to it. I have no issues with the product and would definitely recommend.One other thing I omitted from my original review - the drawstring bag that accompanies the set is very heavy duty and high quality. Not something that will only last a short time. A great bonus. Updating my review to 5 stars.-------------------This is getting a 2 star review because of a significant problem with one of the balls. I have contacted Precision Impact and will update this review if they correct the problem.When I opened the package I had my kid do a feel test to see which ball was the same as a real baseball. Trick question because the set doesn't come with a regulation 5 oz ball! I was curious if he'd go for the 4 or 6 ounce ball. But he zeroed right in on the 6 so I did the feel test too and sure enough it felt just right. Would not have guessed 20% heavier at all.So I broke out the kitchen scale and found the 6oz ball was really 5oz, as were several other real baseballs I broke out for comparison (all with 1/8 oz of each other).Now I normally wouldn't make a big stink over an ounce, but I bought this set primarily to use with a 20% under/overload program so the 4 and 6 ounce balls were pretty important to me.As I said above I contacted Precision Impact. If they replace the ball I'll update the review because otherwise the balls seem pretty decent.For those who are interested, I weighed the entire set. All other balls seem reasonably close to their listed weights (some over, some under). Here's what I found:3oz - 2 7/8oz real weight4oz - 4 1/8 oz6oz - 5 <<< the problem ball7oz - 6 5/88oz - 89oz - 910oz - 10 1/811oz - 11 1/812oz - 11 7/8

exelente me encanto

As advertised. My 10 year old son is using these to build arm strength and velocity. I am not comfortable with him using weighted training baseballs over 12oz. I am hopeful that we can build to heavier weights after routine use of these training aides. He was excited to use them and the effort put into throwing was impressive. Hopefully velocity will build.

Well made and durable. My son is 9 years old, so some of the heavier balls are off limits for him right now. Still, he'e eager to move up and it gives him something to aspire to. Me personally, I'm loving the progress being made in his confidence and arm strength. Well worth the purchase. Should be used responsibly and with a proper program to ensure safety and avoid injury. In all, I am very happy with this product. Definitely a home run.

Ordered these for my college age son to use in his weighted ball training. They have the same look and feel as a baseball aside from the different weights. I do like the different colors as it's a visual que to know which you are grabbing.

They work pretty well but don’t let them hit the concrete, the color and writing peal off immediately. The first time using them and this happened.

Same experience as everyone else. The synthetic material (pleather) is really fragile. The balls will get deeply gouged if they take a decent roll on the ground. Other than that, it is one of the best training tools for over/under training. I am seeing significant improvements in my son's strength. I wish I knew about these a couple of years ago.

They come in 9 different weight of balls in a box with different color of each ball, look cute, also including a nice bag for storing all the balls. My son likes them, they should be a great handy tools for practicing pitching.

Perfect delivery, exactly as advertised
