Bat Pack Easton S3 and Marucci CAT 7 -10 Senior League Baseball Bats: SL17S310B and MSBC7X10

Pros: Anti-Vibration knob, Hot out of the wrapper.

Cons: None

Pros: Switched my son from a Mako to this Marucci for 11U travel and what a difference! His confidence has already increased significantly. The sweet spot seems larger than the mako and has a lot more pop with less vibration. Every time he's finished in the cages, the other players are trying to get their hands on it. It's worth the money!

Cons: None yet...curious how the 3/4 will hold up after a few games but so far, no CONS at all. Great product...very happy.

Pros: Great feel. Big sweet spot. Lots of pop. Looks cool and makes a great sound. My 11 yo went from Rec/All-Stars to travel and wanted a big barrel. This has a great weight on the swing and the transition to a heavier bat was seamless. Hit his first ever homerun (dead center) in his 3rd time up. It has become very popular with his teammates too.

Cons: None yet

Pros: price already dropped from poor sales

Cons: tiny barell bad size translation price already dropped from bad sales do your self a favor and get the posey the barell was an inch and a quarter longer at its max point

Pros: AV2 knob

Cons: Barrel is a little shorter than the Posey. However the AV2 knob is the whole reason to buy this bat. My son used his Posey and dealt with the hand sting all last season. After this tournament with the Cat 7 I asked if he had any desire to use his Posey again and he said no. He stated the Cat 7 didn't sting his hands once. As for the negative comments about barrel length, the Posey isn't exactly the longest barrel either. If your looking for a longer barrel get the HEX connect. If you're looking for a solid bat for a confident hitter this is a great bat to consider.

Pros: My son is 9 yrs old and had a cat 6 and has been a very good bat. The bat has a very good sweet spot. I would recommend very highly.

Cons: none at the moment.

Pros: My son was using a combat 27 -10 and we switch him to Cat 7 and you could tell the immediate difference. The balls fly off this bat and has become a team favorite. So much so that a couple of kids have gone out an purchased these bats for their own.

Cons: None

Pros: AV2 knob Sweet Spot I'm not going to get on here and say this bat made my kid hit big home runs or triples galore. In an honest review, this bat has improved my kids confidence. The sting from his previous Mako and even the 516 are gone. We have probably hit about 800 baseballs with this in practices and he has used in 6 games so far. At no point does he tell me his hands are stinging from hard contact with the ball. This improved confidence has helped him overall improve his avg and slg percentages. He was so worried about the sting from the Mako Beast that he stopped using it. Not with the Cat 7 so far. Marucci has put out some great bats for older and younger leagues but glad this came out now to hit the 9-12u range of kids that just could not swing a -8 or -5 yet or needed a longer bat than a 27. We have the 29/19.

Cons: I dislike white bats-really the only problem so far is being white and showing every stain.

Pros: Bought this for my 10 year old who plays travel ball. Homerun first game used. Multiple other hits to the fence and line drives.

Cons: None

Pros: Light weight , drives the ball farther.

Cons: None

Pros: Good pop. All around great feel and bat.

Cons: Nothing bad.

Pros: It does perform well. My son swings it like it's weightless. He has very quick hands.

Cons: I specifically asked Just Bats was the sweet spot as big as the sweet spot on the Cat 6 and Cat 7 from coach pitch. You can see my question right here online. They said it was comparable/the same. Oh no it is definitely smaller. The bat is too skinny just like the F5. Also the price dropped from $225 to $199 like 2 days after I bought it. But my son still hits deep w this bat. Looking to get a Hex Connect now. A bat w a real sweet spot.

Pros: This bay will not disappoint. Hot out of the wrapper like the old Cat 5. My 11u son put one out 225ft and he is not a big kid barely 90lbs.

Cons: None

Pros: 11U son always prefers 1 piece, but with that comes some sting on occassion. when Cat 7 with the anti-vibration knob came out, we tried it out. Bat diesn't make the players better hitters, practicing good mechanics and confidence does. in my opinion, this bat allows for both.

Cons: Nothing yet. cannot comment on durability yet, but that's why these bats have warranties.

Pros: great out of wrapper, my son loves it

Cons: none yet

Pros: My 9u son absolutely loves the new bat! First pitch at batting practice he laced to LC fence!! Every ball hit was a solid line drive. I jammed him intentionally and he didnt complain about stinging his hands. Kid cant wait to use in tourney. Good job marucci

Cons: None

Pros: Great pinging sound. Can be used in any temperature. Seem to jump off bat with zero vibration. Sons favorite after buying Easton Hyperlite ghost X(2018), Louisville 918(2018) and Marucci F5 (2018).

Cons: none

Pros: The bat has a awesome feel to it, I love it and so do my teammates!

Cons: Nothing

Pros: Great pop and lightweight!

Cons: none yet

Pros: ready to go out of the box

Cons: none

Pros: This bat has a ton of pop!! The ball comes off the bat hot.My son is excited for the season.

Cons: none

Pros: great pop out of the wrap first weekend used ball jumped off the bat second weekend hit it even better very satisfied with the bat.

Cons: none yet

Pros: My son is on the small side. I have tried several bats: the Voodoo, CF Zen, 618 SOLO. I found with him Aluminum bats worked better, but he didn't like the vibration. The only bat that closely compared to this bat was the 618 SOLO, and even though the 618 doesn't vibrate as much, it doesn't have ad much pop as the CAT 7

Cons: Smaller kids like my son will love this bat, but stronger hitters will want to go with the -8. Vibration is a little harsher than the 618 Solo, however it is not bad at all.

Pros: lots of pop, evenly balanced

Cons: none

Pros: great pop out of the wrapper by far the best out there so far

Cons: none

Pros: this is the best model bat in the market hands down. ive purchased several high dollar bats for my son over the last couple years and none come close to the cat 7. our whole 8u team uses either a 27" or 28" version of this bat. you simply wont find a better bat for the money.

Cons: none

Pros: zero

Cons: multiple

Pros: bat has a lot of pop, well balanced, very distinct noise, son likes it

Cons: no idea about durability yet, a little pricey

Pros: Light weight, good all around feel for the kids. so far no cons. but we have only used in 2 different tournaments so time will tell. so far so good. we are happy with the bat!

Cons: none to mention as of now. solid bat!

Pros: bat feels good in your hands. Can hear the difference when you hit it flush.

Cons: None so far.

Pros: No vibration Awesome pop

Cons: none

Pros: Great pop and wide sweet spot. My 10 yo son loves it!

Cons: None

Pros: Great pop and balance. My son is hitting better with this bat than he has in years.

Cons: absolutely none

Pros: Good looking bat and great grip. The sweet spot seems small but if you hit it perfect its great.

Cons: My 9 year old travel baller didnt love this bat and prefers his 2017 Rawlings 5150.

Pros: Bought 27/17 bat for my 6 year old, 7U machine pitch boy. He loves it! Light swing! Great pop! He's now hitting ball to the outfield! very happy with bat

Cons: If anything, price. But its a great bat!

Pros: tons of pop in this bat, looks great and feels great.

Cons: after one weekend of a few 12u players using this bat and hitting 5 homers in the last two games, the bat already has a pretty good dent in it.

Pros: This is the third Cat 7 purchased in my house. The first two were -8 and -5 models for my middle child. Never had an issue with either one of those, just ages have different drops that they use. This 30/-10 was purchased for my youngest child. He has had several composite bats and we wanted to go back to a one piece aluminum and the Cat 7 was the only one we really wanted to go with because of the success we've had with this bat in prior use.

Cons: no Cons

Pros: The Cat 7 has more (PoP) ball speed than the more expensive composite bats and is much better balanced. Younger batters can swing this bat much faster and with better mechanics than a end loaded composite. The bat is ready to go out of the wrapper and just as good in cold weather as it is in warm weather. Try to find a composite that can do that. I promise your Kid will enjoy this Bat and the vibration dampener really works. We had the Cat 6 and was very satisfied and even more satisfied with Cat 7.

Cons: nothing so far

Pros: No "sting" Great pop straight outta the box and with 500+ hits on it Excellent feel Bought 30 -10 for my 9 y/o, now half the team is swinging this thing

Cons: None

Pros: From the very first hit the pop was unbelievable. Now after his first game using it other kids from his have been using it with great results. The absolute balance of the bat makes it feel lighter than other bats of its size. He said thst he hasn't felt any vibration. I would recommend this bat to anyone.

Cons: none

Pros: First time BP with it my 9 year old is hitting tape measure one hop shots to a 215ft fence! The smile on his face is priceless! and he's been hitting with the Louisville Slugger Prime 916 prior to the Cat 7. I definitely recommend this bat to any player.

Cons: He does feel a little sting with fastballs from his coach but feels nothing when hitting a pitch from kids

Pros: pop feel durability and anti vibration knob

Cons: none

Pros: Bat seems to have a lot of pop not just in barrel area. it is extremely balanced. The grip is very comfortable and perfect size for 12 yesrs olds hands

Cons: every kid wants to use it. haha

Pros: Good pop, the weight is well distributed throughout the bat so it is not end loaded

Cons: Nothing

Pros: Good bat overall, good pop but stings a bit, sometimes.

Cons: After about a year lost alot of pop.

Pros: great pop. big sweet spot. feels great. my 10 yr old loves it!! hit his 1st homerun and overall better harder basehits. he has changed nothing about his swing and is crushing the ball!

Cons: none yet

Pros: My son wanted a big barrel bat for 10u and his coach recommended this bat. It is hot out of the wrapper and has lots of pop. There is little to no vibration. This bat is amazing!

Cons: None

Cons: none

Pros: Very good bat

Cons: Vibrating is a tiny thing

Pros: good pop, distinct sound, little vibration, balanced swing weight

Cons: none so far due to my son still getting used to a bigger heavier bat

Pros: good pop and balanced! the ball jumps off this bat!

Cons: non yet

Pros: My son love this bat. First time up to bat and first pitch was a home run in the winter indoor baseball league.

Cons: None to date.
