Affordable and if it breaks you could replace any part for cheap. Great for the quarantine.

[@seepung]

Thank you for this. My DIY kewlus cobra bag feels great! If you have extra pool noodle (you will), cut off thick discs and slide them in between your weight plates at the bottom. No more rattling noise!

[@csquaredboxing]

Great idea I’ll have to do that!

[@tonylom3249]

Finally you make a review on this!! Every time I buy any new boxing equipment I check out your videos. Appreciate you man for making these videos

I made this and am literally super impressed how well this cobra reflex works. Reedy did a wonderful job. He made like 8 prototypes so go show reedy some love

[@csquaredboxing]

Awesome stuff

[@KingCasaba]

I made a kewlus and love it enough to actually consider the fierce reflex bag. I'm sure someone will appreciate my old handy work!

[@reece7713]

How much was it for all the bits do you know?

[@lawdizon9565]

Nice review bro! I built mine a few weeks ago using Reedy’s pro spring. It does not disappoint. Pretty legit!

[@csquaredboxing]

Thanks brother no doubt!

[@lawdizon9565]

@C note Casino If you live in the US, I believe it ships from Canada.

[@astroblemeRC]

NICE! Thanks for this, I’m going to try and make my own using your guide, the ones you can buy don’t seem to rebound like the expensive ones but this one seems to move better!

[@csquaredboxing]

No doubt! 🙏🏼🥊

[@huntingwolf20]

I also did this and made a full body dummy out of pool noodles. It obviously didn't mimic a real punch, but those noodles flinging at you is a pretty cool effect. You have to learn to get inside the lenth and land your own shots. Which I'm short so I need to get inside anyways. In my case I had my pool noodle as an orthodox fighter, and had his left in a hooking motion (but wider than it should have been), and I had his right out straight. I could slip it on and off the base with ease and then add my normal reflex bag target (which was a cheap lighter weight volleyball). It worked real well and was plenty fast enough for me at my older age now.

[@phillewis3108]

Nice review. Nice “collab” from two of my favourite KZbinrs. The open coil spring is the secret. That’s why Garcia’s is good and many others are disappointing. The value for money of this is amazing.

[@csquaredboxing]

Thanks and I agree hard to beat the value

[@huntingwolf20]

I've been watching you and Reedy for at least 2 years. I screwed up my first build buy trying to go too cheap and my screws went through my base and absolutely destroyed our living room floor with a few punches before...well, my wife noticed. Lol. She almost killed me so that was the real test of my reflexes.. I have since made one better.

[@csquaredboxing]

😂

[@SydeshowMO]

Nice... I was hitting a cobra reflex last night. Gonna pickup that spring and get the hardware! Love the channel!

[@kevinngo9138]

Most people prefer a double end bag but for all of us who can't set one up because we can't hook things to the ceiling, this kewlus bag is amazing! It brings the price of a cobra bag super low and Imo this one is fast enough to be compared with double ends.

[@csquaredboxing]

No doubt!

[@wozzer2727]

That's great, the secret seem to be in the spring, less winds in it is the faster the rebound, I would be tempted to get a proper speed ball type top, but I know the idea is to make as cheap as possible, top job!

[@csquaredboxing]

thanks!

[@fsan5382]

I've tried the ryan garcia bag and I'll let you know the kewlus spring outperforms the ryan garcia bag which is $500 and you can build your own for under $150

I saw a vid w/ the ringside cobrabag where the guy put an inflated bag and it moved a lot quicker

[@danmclean7375]

Another banger! Nice rebounds, quick and snappy-to-centre in comparison to some flimsy lookin' name brands... weight would be the most costly... portable clampmount for the spring to railings or fixed objects could be nice.. and portable.
