Really Light, well made and Super-Fast!!! Best Cobra Flex on the market!!! Our members love this bag, Everyone also loves the easy adjustments for various heights. I highly recommend this bag for home use and/or gym use. It will take your hand speed to another level!!!!
I had been searching for a cobra bag for some time, have used different ones in several gyms, none come close to the quality of the kewlus. I went for the k3 free standing with the base and sand bags. Very fast shipping to the USA, nicely packaged, easy to put together, the spring is excellent quality and the sandbags work exceptionally well negating the need to buy extra weights. I use this everyday to train and don't get bored! I will likely purchase the air free bag soon to add to the kit. I love supporting entrepreneurs like reedy. Great job!
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.
First, great service from Reedy. Fast order fulfilment and shipping. Kit arrived in perfect condition. Second, extremely easy assembly and quality is excellent as advertised. Third and most important, performance of the Kewlus cobra bag is outstanding! Fast, responsive and with two 50 lbs bags of sand on the platform paddles, it's ROCK solid and doesn't not budge no matter how hard I hit it ( and I weigh about 205 lbs and boxing for 5 years). My main goal was to use this for head movement when training alone and the fully adjustable features allow me to get both fast return of the bag AND it will hit me hard in the face if I don't move my head!! This is no toy and it meets or exceeds the performance of much more expensive cobra bags
I love everything about this product. I’ve used a few other cobra bags, and this one is by far the best. The ability to make different modifications make it second to none.
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.
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 !
I have tried several different reflex bags. Some were very expensive. I sent them all back. The Kewlus bag is by far the best. Very stable and responsive. Provides a great workout!!
After looking around the Internet at cobra bags and solutions I came across Kewlus and Reedy’s YouTube channel. After seeing pricing and the modular design I pulled the trigger on a full kit with the KS3 and gloves and I’m blown away by the product, design, and usability. The modular design allows it to be easily portable and the performance is beyond. I’ve got 3 friends looking to purchase now as well. Cheers to Reedy for an amazing product and continued development.
It is definitely one of the fastest COBRA bags I’ve had . I’ve had ringside and title cobra bags also Amazon cobra for $260 dollar and the do not compare. It’s easy to take on the go to going to order more for gym
Amazing design and easy assembly! Extremely sturdy and is definitely built to last even through the most rigorous training sessions. Would definitely recommend to anyone looking for a cobra bag.
I have taught martial arts/fitness classes for 40 years and have the ringside cobra bag andI am an equipment junkiie that has purchased lots of training equipment through the years. I found the ringside bag so slow but the Kewlus bag is far above my expectations. Thank you for listening tp buyers and creating a wonderful training tool. My wife uses it as well.
This cobra bag is great. Everything is high quality. Better way to go than amazon and others
Everything with my order went perfect, arrived 2 days earlier which was awesome timing! The set up was super easy, quality materials, great price. All in all I'm excited to use this product. I am a first time Cobra Bag buyer, after doing some research I felt like Kewlus was the best option. Thank you Kewlus, keep up the awesome work 💯
Got it few months ago
Loved how it works, everything in the package is made with high quality materials
Really had fun with this Cobra bag !!!

Kewlus Red Bar
The Red Bar has been designed to increase the speed of the Kewlus Cobra Bag. It's specifically made for switching out the Click Bar in the top section of the cobra bag. The Red Bar is 3 inches shorter than the Click Bar and almost 1/3 of the weight, resulting in a much faster cobra bag.
