Bat Pack Adidas Aero Burner Comp and DeMarini CF Zen -10 Senior League Baseball Bats: AEROBU and DXCBZR

add_circle_outlinePros: Is balanced the same as the CF8 (green bat). Not a lot of sting. Seems to have a good sweet spot. Very close to the original Zen but noticeably less pop.

remove_circle_outlineCons: Noticeably less pop then the CF8 and the illegal Zen. I contacted demarini and was advised they used a "ceramic sleeve" that was inserted into the barrell. This stiffens up the barrel and restricts the "trampoline effect". We hit about 150 baseballs outside and the bat did seem to heat up the more my 12u travel ball son hit with it. He liked it even though the pop was less. He uses a CF8 during his games and had the illegal Zen as a back up. He wanted the retooled bat so we bought a new one with the voucher money.

add_circle_outlinePros: My son loved the performance. Very easy warranty process.

remove_circle_outlineCons: We purchased a new CF8 for the Elite 32 at Disney last July, unfortunately by the end of the tournament the bat was already cracking. We went through DeMarini's warranty process, and was issued a voucher number for a replacement. In April we ordered a new Re-tooled CF Zen (performance was not as good as the CF8 but still very good) Sadly like the CF8 within a few weeks it cracked. While I understand DeMarini's warranty policies and I'm thankful for the first replacement, I still feel that a company should stand behind their product especially one that fails within the first few weeks. As a guy that works hard for his money I can no longer afford to spend the kind of money that DeMarini charges for bats that are less durable then their competitors

add_circle_outlinePros: My 12u son loves the feel of the bat. not much vibration.

remove_circle_outlineCons: Less pop. Bat busted in less than 2 months.

add_circle_outlinePros: i like on how it feels

remove_circle_outlineCons: the look

add_circle_outlinePros: for a brief period, there was decent pop, but soon after it started cracking.

remove_circle_outlineCons: no durability. this is the third CF8 in a year. Last years CF8 broke in the cage within two days. once returned, received the illegal CF8 then the retooled one. after 4 tournaments its cracking. my sons buddy had the same experience. appaently these bats are not made for tournament players. ridiculous for the money spent.

add_circle_outlinePros: it's got a big sweet spot

remove_circle_outlineCons: the first day I got it it snapped in have. I would go with marrucci

add_circle_outlinePros: Great bat with great pop. Not sure on durability yet.

remove_circle_outlineCons: Plan on this bat weighing at least 2oz more than advertised. I put my boys on the scale and his 30/20 weighed in at 22.17. Still a nice bat, but really a drop 8. Should have probably went with the next size down.

add_circle_outlinePros: This bat is by far the best bat DeMarini has ever made.

remove_circle_outlineCons: Zero so far

add_circle_outlinePros: Still has a nice pop and nice feel to it.

remove_circle_outlineCons: Bat weighs 3 oz over stated weight. Too heavy for my 9-year-old to swing. Demarini Customer service told me it's because of the ceramic sleeve applied to the inside of the bat.

add_circle_outlinePros: Great pop! Retooled version is legal for all USSSA play.

remove_circle_outlineCons: My son is having a hard time getting used to the sound. This bat is not your typical one piece aluminum or alloy.

add_circle_outlinePros: It has a lot of pop and it was fresh right out of the box i love this bat tho

remove_circle_outlineCons: some of the reviews concern me about the bat snapping and craking

add_circle_outlinePros: Good pop

remove_circle_outlineCons: A lot of money for a throw away bat. I coach a 11U Travel team and we have had 4 Demarini bats break in last 2 months all of the bats were less than 6 months old!! Getting a 2019 with a voucher praying it last a season, if not ill never waste my money again on these products or guide my players parents towards Demarini.

add_circle_outlinePros: Best bat i'v ever used

remove_circle_outlineCons: Cost a lot

add_circle_outlinePros: the bat hits bombs and has no sting.

remove_circle_outlineCons: is breaks really fast

add_circle_outlinePros: Even though this is a retooled bat it seems to have some good "Pop" in it.

remove_circle_outlineCons: You may get some push back at tournaments about this back being ban but it has the the "R" and an orange end cap to show it has been retooled and it is legal for USSSA play.

add_circle_outlinePros: This has been a great bat. My son loves the feel and it is driving the ball much better than his COMBAT. I don't allow him to use it below 60 degrees which I think helps with durability on the composite. They get brittle the colder it it. Price was great and we are very satisfied.

remove_circle_outlineCons: None

add_circle_outlinePros: My son has wanted a "De Marini" - meaning a USSSA Zen - since he started playing travel. These bats have a huge following - the kids worship them. Well, at this price point, I could get him what he wanted without missing a car payment, and the bat is fantastic. We did the break-in precisely (200 1/2 speed swings, rotating 1/4 turn each time), and the bat is holding up well and hitting bombs. He is a big strong kid and a good hitter, and when he squares it up, the ball is gone in a hurry. Overall, the bat is: - "Hot" - the ball jumps off of it - designed with max contact area - the barrel stays at the max diameter over a large distance - reduces vibration to the hitter's hands - a tremendous value

remove_circle_outlineCons: Understand these composite bats have a life expectancy - they will all crack given enough swings and under certain environmental conditions. Control what you can. Only use it for games, not practices or BP, don't let teammates borrow it outside of games, you get the idea. It's like anything else - take care of it and it will last longer. It is well balanced, but a little heavy toward the end cap, which can cause weaker kids to develop bad swings where the barrel lags behind the hands. If your player is not on the stronger side, opt for a shorter length, which will make the bat lighter and easier to swing. I see a lot of kids swinging bats that are too big for them. You put a smaller bat in their hands, and they become totally different hitters. It's not everything, but it definitely can make a difference. I'll take bat speed over plate coverage any day. Overall, I don't see a lot of cons here. It's a great bat - but like all composites, it will break eventually.

add_circle_outlinePros: very balanced

remove_circle_outlineCons: grip slips when hands are wet

add_circle_outlinePros: After reading other reviews I chose this bat for my son to use for this season. With the insert it dors swing like a drop 8, but it was bought purposley for that reason. We are using it as a transition bat to get to a drop 5. Extra care was taken to get the proper break-in and my son put in roughly 200-250 medium swings between the tee and soft toss before use. It was then used for two regular games and continued to heat up to the point where multiple players on the team are now using it as it has become pretty hot. We did not have any previous experience with Demarini composite bats as I have been a Louisville Slugger person, but so far I have been impressed with what I have seen the bat do.

remove_circle_outlineCons: Even with the extra care to break in, I have already saw some nicks in the bat that make me a little leary as what to expect from the durability. There have not been any problems through 3 tournaments with multiple players using the bat, but I want to see if it lasts the entire season. At the price I bought it for I will not complain if it doesn't last, but it might hold me back if I had to purchase one at the full cost.

add_circle_outlinePros: the feel

remove_circle_outlineCons: My son "broke it in" like he was supposed to the first day he got it. Bat broke the next day during the first game of the tournament! They sent a replacement, and it broke the next weekend! Way too much money for bats not to last.

add_circle_outlinePros: My boys love these bats! great feel ans pop!

remove_circle_outlineCons: they do break down pretty quick

add_circle_outlinePros: grip is great, the pop will knock you out,

remove_circle_outlineCons: none

add_circle_outlinePros: great pop out of the wrapper.

remove_circle_outlineCons: barrell cracked within the first week.

add_circle_outlinePros: hot bat out of the wrapper with plenty of pop my son said the balance is on point and it isnt too heavy or too light, no stings or vibration in the bat. a remarkable bat and jts not even fully broken in, cant wait to see what it can do when it is.

remove_circle_outlineCons: none so far!

add_circle_outlinePros: Does not vibrate bad, good pop and looks cool. Dad.... after about 300 hits, bat still does not out perform the cat7.

remove_circle_outlineCons: As of now none to mention. just that composite bats are slow to break in.

add_circle_outlinePros: The pop was great, it was very comfortable in the hands and allowed for a great swing motion feeling very balanced.

remove_circle_outlineCons: Durability ended up being the issue with this bat. At just under 5 months of use, with proper break in per the manufactures suggestion and never using the bat in conditions under 60 degrees F. the bat came apart at a tryout over the weekend. My son is not a power hitter by any means, and is only 5 feet tall and 115 lbs. We now await the warranty process. It is a great bat until it comes apart, which at less than 5 months of use is a little scary.
