Highly recommend grabbing yourself one of these ks3 cobra bags!
Pros: Very high quality material.
fast and responsive.
Easy and affordable to upgrade with its modular abilities.
Keeps up with other professionally used bags such as fierce. (Sorry if naming other brands is not ok).
Great for beginners as you can adjust the speed with a simple click until you catch on!
Cons:
The only real downside which is fixable and not a big deal is the squeak, because all the metal bars click together, if you hit it on edge it turns the bar slightly causing a squeak. (Easily fixed with a tiny bit of grease on the bars)
Recommend grabbing yourself the red bar with your order for later use as it’s not very expensive and will save you delivery fee later when you want more speed!
The owner Reedy is super helpful and has lots of helpful videos which makes me support this brand even more!
I absolutely LOVE my Kewlus bag. I get an amazing working, I'm dripping sweat after just 10 minutes punching it, and i have a blast! Outside of the set up being awesome, the customer service is Outstanding! I had a leak in one of the bladders so I reached out to customer service, and a replacement was sent out that day, no questions asked. When you have an amazing product, and amazing customer service, you're bound to build a huge business, and I will always support this company due to the way they have treated me. It's so refreshing to have a company that actually cares about their clientele. If you're looking for a great workout thats fun and helps improve you ability to hit a moving targer, INVEST IN THIS SYSTEM TODAY!! Thanks Kewlus team, y'all truly do rock!
Glad I purchased this bag after going back and forward trying to decide which to purchase on the internet (so many these days to choose from happy I chose Kewlus).
Why is this bag so great and how does it compare to others?
Kewlus bag is modular as stated but moving it into the corner out of the way is very convenient when you use the kewlus sand bags vs. a competitor cobra bag that uses a fillable base (for me it's easier to move some sand bags instead of a base of water filled or sand filled container where it's purpose is to not move).
The leather bag is very well made (smells great when you remove it from the shipping packaging) and it's built to last, no cracking after owning it for 6 months now, plus is it's replaceable! There are other bags in the same price range do not have a bladder and don't have replacement bags available. It's also a bit lighter in terms of weight so it doesn't fling around on the base that holds the bag unlike other cobra bags. I've noticed I haven't had to pump it as often as a result compared to a competitor cobra bag at the same price range.
Lastly, Kewlus' customer service is also five stars. Reedy was quick to respond to my questions and kind enough to send me a replacement part when I broke a piece (it could have been my fault but Reedy sent me a confirmation of a replacement piece right away via email with shipping info.)
Overall, I am very happy with my cobra bag and can't wait to see what else Reedy has in store for it.
Absolutely brilliant system , my son loves it and the ease of setting up where you want to use, and to be able to pack up and put away. Top product , highly recommend to aspiring boxers, well done Reedy
I did some online research and almost purchased the Grodex Cobra Bag. I'm so glad I found the Kewlus Cobra Bag instead. I can't recommend the Kewlus Cobra Bag enough. The quality is top notch and very sturdy despite the modular design. I was expecting the product to be flimsy, but I couldn't be more wrong. I have practiced martial arts for over 10 years and can hit a bag with decent power. The Kewlus bag held up fantastic so far and rebounded quickly with the heavy duty spring. The Customer service at Kewlus is unparalleled! Reedy was very responsive to my inquiries even post sales. I won't hesitate to buy Kewlus products in the future for all the reasons mentioned. Awesome product! Thank you.
The KS3 spring is just so incredible fast and has a really great rebound while still not missing out on reach, so it's perfect to work on my Philly shell.
The fact that the whole bag is modular makes it even better. I'm pretty tall, so I might replace the lower click mast with a galvanised pipe to use the shortest/fastest setting of the bag.
It's just a quality product and you can't anything better for this price, plus the customer service by Reedy is top notch.
Love it. The KS3 spring makes the bag faster, easier to adjust height and overall more fun to hit.
I love this bag. It really trains my eye hand coordination. I also think the quality is very high as well. I definitely recommend.
The Air-Free bag is a great add-on for developing a stronger punch. It's a little slower and heavier to hit. Feels more like hitting something solid and good for developing the hands and arms. Due to my work and schedule I use not only boxing gloves, sometimes MMA gloves and even my bare fists a few minutes here and there as I pass by the Reflex Cobra Bag. My home and work place are the same space.
The Red Bar definitely gives more speed and changes the training. It's also easy and fast with a simple swap out. I like to switch things up and change the feel and response regularly. The Air-Free bag is also excellent for that. Although not as fast as the pump up bag it definitely has a harder, more solid feel providing greater resistance to the punch.
This is the only modular Cobra bag. VERY quick and easy to set up, extremely fast spring and quality parts. I love this product, and the service and communication from Kewlus is exceptional. I highly recommend this product! I've tried several other cobra bags, this has been the best of the bunch.
This is the best unit I’ve used I’ve tried 4 different brands until finally finding the one that I’m happy with I run a boxing gym about 40 fighters hit this daily and it is very durable and these guys have great customer support I’ll update a video soon of us hitting it
Thank you Kenny for your review!
Most used piece of equipment in my home gym everyone who sees it wants to use it . Quality made to take any punch Iv'e seen so far . This is a must have for someone getting into cadio workouts make exercising fun .
I was looking around for a cobra bag that would not break the bank and the kewlus kit is probably the best option. From the youtube videos that I have watched of other cobra bags, it seems there are none that even come close. I have been enjoying it and so far have no complaints.
My Fierce cobra bag failed. Seam split. Could not get replacement from Fierce. Sold out. No availability date. No response from customer service. Found perfect substitute with Kewlus cobra bag. Perfect fit. Better quality. Extra bladder included. Will never buy Fierce brand again. Big mistake buying Fierce in first place.
I had a problem with my adapter. I contacted Kewlus and they more than made things right. I cant believe customer service like this still exists.
These suction cups have saved me from having to use a heavy base. I use them to set up the Kewlus cobra bag in my garage, where I painted a section of floor just for this purpose. Quick to set up and when I'm done smashing the cobra bag, they are easy to put away. I also use the suction cups to mount the cobra bag horizontally on a laminated board that I have attached to one of the garage walls. That way I can work on hooks and uppercuts, as well as my cardio.
Don't hesitate and go for it.
Good quality.
Much fun to use.
Nice guy behind the product.
I’ve wanted a reflex bag for years and was finally about to pull the trigger between a grodex or a fierce reflex bag.. Happened to stumble across Kewlus and saw that this new version dropped a few weeks ago. For half the price, this does EXACTLY what the more expensive ones do.. and the quality is THERE.
big respect to ya kewlus !
The KS3 core kit was a present from my missus!
Really impressed with the construction and ease of set up.
The spring is fast and it's a fun and challenging workout.
Very very happy.
Shipping was only 7 days and that was to the UK.
good price and worth every penny.
I'm a professional boxing coach and although this is for my own use at home, I'll definitely be taking it to the gym as well so my boxers can have a go!
Easy to set up and definitely one of the best reflex bags on the market. I had my base drilled to my garage floor, so all I do is remove the pole when I want to park my car.
Overall happy with the purchase. Wish the action was faster, but overall happy.
Thank you Henry. You can now upgrade to the new KS3 Spring to make your cobra bag faster!
Overall, Spring reflex action is good but DIY build can be improved. Some of this could be be me but want to share issues I ran into during build.
1) Finding a 3/4 & 1 Inch metal pipe that fit between each other is tough. I tried HD, Lowes, Menards, etc and didn't have success. I spent 3-4 hours using hammer and sanding tools/brushes to make things bit more manageable.
2) Butterfly clamps are good but need something more sturdier. Jabs are great but if you plan to mix Jab with uppercuts you might send the pvc pipe flying upwards. I have to hold back power on uppercuts to overcome this issue. My thinking is that better or more clamps are required to overcome this issue.
3) I have no vibration or sound when I use the bag which is great. If you pay close attention to the build it should be mostly sturdy.
4) I did not build circular base and choose rectangular shape so I could put two 55 lbs plates (total 110 lbs) on the base. I attached flange to a rectangular shape pressure treated wooden board (approx 1.5 inch thick and 10 inch by 40 inch). I am realizing circular base would be better. I will rethink this later.
5) Note, with amount of time spent to get the metal pipes to fit in one another and $'s spent (Metal Pipes, pvc pipe, flange, pvc connector, butterfly clamps, bag, spring, duct tape, funnel, screws, and wooden board), I would highly recommend just buying the whole kit vs spring. Now, if you have some of these things at home already, then you may find it beneficial to buy spring and build. This was not the case for me.
Lastly, let me just point out that the bag is so much fun. I have gotten smacked in my face a few times but still enjoy very much. Thank you
