Pros: The prime feels amazing no vibration at all
Cons: Unlike the 916-917-918 this bat does not have pop at all i got to hit with it on the field at our local college when they had demo day with the bats,all though it feels amazing it took me everything I had to hit it out.I would recommend the select 719 or the omaha.With those bats balls fly out of the park with ease
Pros: Great Pop off the bat. Great Feel and little to no vibration. Bought this bat for my son this fall and he loves it. Other kids have used the bat and loved it so much it has pretty much become the team bat.
Cons: Con for me is always the cost but not much we can do about that.
Pros: no sting
Cons: Tbh i would rate this bat a zero star if I could.Literally no pop.it seems personally that the people that like this bat are rich dads or kids that just aren't strong at all.This bat is the beginning of the end if the primes continue like this.If you want the ball to go anywhere and composite either get a 917/916 or the meta prime.And the price for such bad of a tool is ridiculous.)0/5
Pros: The bat does not sting at all
Cons: No Pop,there is no pop out of the wrapper and no pop when taken 400-500 reviews i thought the people giving them bad stars on here were being stubborn but no they are right it is not worth the price please listen to this review save your money
Pros: Eventually the bat will have POP. Very balanced and durable. I too was initially very upset for spending $450 for a bat that was hyped as the next best thing but had no pop. We had to break it in really good and that took 3 weeks and 1000 hits. After breaking in, the bat is living up to all the hype. Tested exit velocity off this bat and two other Alloy bats and the velocity was better with the Prime.
Cons: Initially was upset and dissapointed. It takes a good 3 weeks and 1000 hits to break in. This bat reminds me of last years Demarini — takes forever to break in and has no sound off the bat so it’s like hitting with a wood bat. Last years 918 had pop out of the wrapper but the 919 doesn’t but will eventually get there. I’m not sure how this bat will hold up in cool weather because the feel out of the wrapper was like hitting with a concreate bat. The bat feels good now after breaking in but I’ve seen bats in the past crack that started out with the same feel as this one so I’m not as confident with the 919 as I would be with others.
Pros: I bought this bat for my son who's playing 13u moving up to 14u this August to use with his travel ball team. The goal was to get him swinging a -3 bat now so he's ready when they move up. The feedback from a 13 year old is the bat is solid, no vibration, and has good pop so far. Has not been used in games yet. More feedback to come but so far, we're very happy. My older son swings the 918 Prime and it's a beast and still going strong.
Cons: None so far but time will tell.
Pros: I brought the 31 prime for my son who is 12yrs old, but will be 13 soon. I’m a softball player so I made sure I was hitting with my son during bp’s so I would understand what he’s saying and feeling. It took 500+ hits, but the ball rockets off the bat. My son and I love this bat. My son wishes the bat was more balanced, but he hits the ball hard and I make sure he swings the bat daily so he gets used to the weight & the feeling.
Cons: You won’t like this bat if you are not into end loaded bats. Big difference in weight that my son just came out of Majors and Bronco league with USA bats.
Pros: This bat is sick. I hit on the field yesterday and the pop and feel is unreal. I hit with the Cat 8 the few weeks before and hit nothing out during BP but yesterday I hit 3 out with my fresh out of the wrapper 919. It has so much pop out of the wrapper and the feeling when you square it up is unreal. I even hit one out without hitting the sweet spot. I think this is the best Louisville bat yet and I had the 917.
Cons: 917 went dead very early and I’ve read similar stuff on the 919.
Pros: I am a high school player right now but I am already committed to play baseball in college. This bat takes about 200 swings to get broke in but this bat has a lot of pop. I am hittings balls over the fence like it is nothing. I highly recommend this bat
Cons: none
Pros: This bat has great pop my son got the 919 in the mail this afternoon he had ten batting practice swings fresh out of the wrapper and hit a walk off home run great bat!??Don’t know what all the stink is about this bat
Cons: N/A
Pros: Great pop and comfortable grip, great feel and balance in bat when swinging. Taking live BP off a kid who was maybe throwing 70 and just going through my mechanics and hit 2 home runs first 2 pitches.. bat is crazy even when i face others who use it
Cons: not a con i can think of
Pros: This bat has ridiculous pop. Take a few hundred swings before reviewing. We have this and the meta on our team and the prime is preferred. Ball jumps as if it’s not a bbcor. Size and bat speed may play a part of you’re finding it to be “popless”. Durability is yet to be determined as we’ve only had it a couple weeks but I had to write a review given all the negative reviews about it not having pop. It’s got amazing pop. And this is coming from a family who only used CF8’s the last several years. We know what pop looks like.
Cons: None at this point
Pros: 1- Customer service at Just Bats is fantastic. Had a problem on a used bat, and they made it right without hesitation and we agreed on a fair price in the next bat. The bat itself is great too. Son went 4/8 in first tournament, right after getting the bat.
Cons: None so far..
Pros: Slight endloaded feel compared to other composite bats. It gets through the zone pretty fast and trust me, there is pop. If you have properly broken in this bat you will not have any problem with this bat. Always keep it in a warm place and you should be good
Cons: Obviously it takes time to break in a composite bat, but other than that it is great

About the Brand

In 1842, J. Frederick Hillerich emigrated with his family from Baden-Baden, Germany to the United States. Eight years before, the 1834 Book of Sports had made its debut as the nation's first publication covering baseball. But when he arrived in Baltimore, J. Frederick Hillerich would never have dreamed of the future impact his family would have on America's favorite pastime.
After a short while, the Hillerichs moved to Louisville, where J. Fred started a woodworking shop in 1856. Two of his sons, Adam and John Andrew "Bud" were born in the United States and would later join their father in his business. By 1864 "J.F. Hillerich, Job Turning" was in operation and filled orders for businesses by custom-turning everything from balusters to bedposts.
The firm thrived, and by 1875 the little woodworking shop employed about 20 people. In 1880 Bud Hillerich, who was an amateur baseball player, became an apprentice in his father's shop. Young Bud made his own baseball bats along with bats for several of his teammates.
The debate over the origins of the first bat continues to generate controversy among baseball enthusiasts, but the younger Hillerich was most certainly involved in getting his father's business involved with what would become the company's signature item. According to company legend, the first bat was turned by Bud for Pete "The Old Gladiator" Browning in 1884. Browning was a star on Louisville's professional American Association team - the Eclipse. On a spring afternoon Bud, then seventeen, witnessed Browning break his favorite bat. Bud offered to make a bat for his hero, and Browning accepted. After the young wood shop apprentice lathed a quality stick from white ash, according to the story, Browning got three hits with it in the next game.
Louisville Slugger gloves are worn by more pitchers in Major League Baseball than any other glove.
