Delme D.

Fast delivery, very happy with the quality.

Christopher H.

Ordered and it came within a few days , easy to assemble and very good quality, got training straight away I love it

Wayne D.

Great reflex ball well worth buying. Once you get used to it you can really give it some hard hitting with loads of different combinations.

Marcel B.

the speedbag is finally something sensible. I ordered one from Ringside and a Fierce Reflex from the USA and the Fierce is the biggest piece of junk ever. THE RAPZ IS great, it is at least as fast as the Fierce... but much better made. So keep your hands off the junk from San Diego, buy a RAPZ!!!!!!!!

Leigh n.

Exactly what it says on the tin. Great on hard floor haven’t used anywhere else but it’s great on that.

Zoe A.

Very easy to assemble and sturdy just filled with water. Great piece of kit.

Richard K.

Great bit of kit. Had a floor to ceiling bag before but I find this a better workout. The smaller ball makes you concentrate more. I filled the base part sand/water as it would of taken ages to filter all the sand through the hole. Is there an anchor weight available to add extra weight? I use my 20kg vest over the base but need a more stable weight addition. Overall love it

Manjit

Very pleased with the product but it came after several months whereas it was for my son’s birthday. Even then I had to do a lot of chasing. But as I said, 5/5 for the product

David S.

really great workout with great eye to hand coordination

Paul G.

Great bag, good quality construction. Once you've set it up properly, it does take your training to the next level. It's great fun, so keeps your motivation to train up too.

Marcin S.

Very helpful, good quality

Matthew M.

The Reflex bag is better than expected, i’ve used everyday since arrival, Ive seen massive improvement in timing and power from it..

Chris B.

Took a while to arrive, however Ash did keep me updated with the order progress throughout so happy days. Well built item, easy to set up and the suction pads on the bottom are like gorilla glue on a flat surface, hardly any movement, even though I haven’t filled it part with water yet. Chris.

Cooper M.

Never leave reviews but had to about this piece of kit, been a boxing coach 30 yrs and have had a few reflex balls over the years but this bit of kit is best by a mile very responsive and even without filling base with sand or water didn't move as suckers on base made it stick to floor like glue

Rod M.

Had another manufacturers ball which was good. But this one is better faster great product at a great price.

David S.

excellent product, highly recommend. works on reactions and defense immensely

David M.

Quality bit of kit punch fuck out of it

David I.

This is a fantastic piece of kit for any beginner upwards. Great fun and definitely encourages improvement on hand speed and accuracy worth the outlay the components are quality and it’s easy to piece together can’t speak highly enough of this purchase cheers

Jacob D.

Very good bag love it

Stephen S.

Great

George J.

Anyone who loves the sport of boxing needs one of these. Amazing for hand speed and head movement. The bag comes back at you so fast that your forced to react quick to dodge it. This is what you call a piece or equipment that makes you pay the price if you mess up a combination!

Hasan R.

As a retired boxer, I really wish we had one of these growing up. This bag is an actually masterpiece of engineering. The bag is sturdy, the grips underneath do an amazing job and the spring is just unbelievably quick, it is the only piece of equipment I’ve had that has really tested my limits.

Kourtney C.

ABSOLUTELY LOVE THIS BAG!! I use it indoors as i live in a flat and it’s perfect for getting that extra bit of training in when i want a quick burst. Really improved my hand and eye co-ordination and overall fitness levels. Very impressed with it. Would recommend for sure.

Tory R.

This reflex bag is amazing. It was very easy to put together also it’s very sturdy and well built. I use it everyday with no problems. It’s perfect!! everything I was hoping for and more. If your in the market looking for a reflex bag, I highly recommend this one. I did a lot of research trying too make sure I got the most for my money. And lets just say this bag exceeded all expectations that I had. Very pleased!!

Brad W.

I don’t think anyone in the house can help themselves punching my bag every time they come into the kitchen. Honestly very happy with it, its addictive, fun and definitely difficult to start with, but once you get use to it you will definitely start to see major improvements like I did.

Ben R.

Fantastic bit of kit!!

Adrian B.

Great quality and robust, nothing short of perfection, highly recommended to everyone from beginner to professional

Louis E.

I haven’t had much time to use product fully but it solid and can take good shots!

Mustafa A.

This was an amazing bag, very high grade stuff. Everything works amazingly

Carlos H.

BRILLIANT! 10/10 from me and all the kids at the gym. I bought this for the boxing gym that i own as the kids kept pestering me about wanting to try it. They all love it!! i only bought one to try but i will be purchasing more later this week for sure, and then more of them can have ago at the same time. It definitely keeps them on there toes when it bounces back at them.

Claudimar W.

As advertised! No complaints! I filled to the maximum with sand. Made my height adjustments and it has become an everyday item of use. Extremely satisfied with this product. I can land my punches, uppercuts, hooks, knees, elbows, and kicks!!! It is amazing for accuracy, hand eye coordination, dodge reflexes and more. As you work out with it, you'll personally add and create new workouts to fit you personally.

Billy J.

This is a very high quality cobra bag!! I use this bag almost every day. I’m 240lb and 6’1”. I’ve been boxing recreationally for 20 years and I needed something at home that didn’t take up a ton of space. I’ve been hitting this thing for almost a year and it’s still holding up like it did on day one and I hit fairly hard. I love it and recommend it to anyone who has intermediate experience boxing. Maybe not the best idea for a first timer because this thing hits back, which is actually my favorite thing about it.

Kayla W.

My boys love the boxing bag as does anyone who walks past it, no one can resist a quick hook. Overall very good bit of equipment.

James V.

It’s a great fun piece of training equipment I’m not a boxer but enjoy the workout it gives me, I’ve been watching pro boxers using them on YouTube to practice and develop techniques, it’s well worth the money

Toni M.

I bought this for my son for his birthday. Ever since watching Jake Paul become a boxer, he is adamant he wants to train and be like him. So yeah he loves it, he has just recently started boxing as a hobby and this is a brilliant piece of kit to help him progress further. Totally worth it :)

Richard P.

Extremely happy with it since it arrived. I was very impressed with the build quality, the spring is solid and it was a nice surprise to get a spare ball included. Excellent piece of equipment for the price would definitely recommend.

Jane A.

I treated myself for my 50th birthday. I don't have space for lots of training equipment and this is perfect. Ideal height adjustable (I'm 5'8").

Kate W.

Super fast delivery. Bought this to replace an existing bag we had to keep us going through lockdown. Wow what a difference! Excellent piece of kit.

Logan P.

Fantastic bit of equipment, great for improving reflexes, it’s actually a lot harder then it looks but I am getting better

Mick J.

Brought it for the family and its so much fun, kids can’t get enough of it. If you use on carpet definitely recommend putting water in it for added weight.

Will B.

Great fun!!! The bag is incredible for the price. Love to it use it after a long days of work to get the stress of my mind and very polite customer service

Ralph B.

Just finished installing it and im definitely impressed. Took me 10 mins to setup. Instructions are easy and straightforward forward aswell. Its much harder than it looks definitely need practice

Harry S.

I've literally set it up in my garage. Sick bit of kit, exactly what I wanted, best one anywhere for the price. Customer service was brilliant.
