Century Original Wavemaster

Great product easy to assemble. Works very well. Does not tip over if you put sand in the base. Definitely cannot use water or it will not be sturdy. Been using it for a couple months without issue.

As a Muay Thai mom to a Karate kid. This keeps us both busy. Love it. We filled with sand and it took a bit of time even with our large funnel but I prefer to fill with sand. It’s very durable and great quality. The weight is great and the size is full size and perfect for what we do.

Moderately good product for a moderate price. Filled with 250lbs of play sand and withstands Muay Thai kicks. It does move a bit but if you circle around it as you train it should easily stay within a 3’ circle. Recommend minimum 6’ radius work zone from center to train comfortably.

I'm only writing this review because it seems like neither the reviews nor the manual do a good job of illustrating to people the difference between water and sand when it comes to filling the base. The base has a capacity of about 33 gallons. A gallon of water weighs about 8.3 lbs and a gallon of dry standard sand weighs about 13 lbs. Sand is a little more than 1.5x as heavy as water per volume. Going with sand allows you to put more weight in the base per volume. Also water, as a liquid, is going to carry force throughout the water meaning when you hit the bag it will generate waves in the water within the base. Sand on the other hand is solid and will deaden the force not allowing it to carry throughout the sand in the base nearly as much. Sand does a better job of reducing the force that acts on the base from hits the bag takes, meaning it is even less likely to slide around. I'm 6'3 220lbs and I put 250lbs of sand in this base (which is a little under 60% full) and it stands on a concrete floor so there's not a ton of friction and I can open up on this bag without it moving very much at all. The bag height is perfect for my height I would say at about 6'6 this bag may start to be a bit short for you, but everyone around or under my height will probably enjoy this size bag. If you want there to be absolutely zero movement you can grab a thin rubber mat, like what you would place under an elliptical machine, which will adhere great to most smooth surfaces (i.e. concrete, tile, hardwood, etc.) and that should solve most of your issues. If you do decide to go with sand be sure to grab a funnel at Home Depot or where ever you buy your sand at, it'll make filling the base way easier. The manual will tell you to use the bag as a lever to help you distribute the sand within the base, I'd say skip that and just replace the lid, grab the base on the side with the opening and lift with your legs to re-distribute the sand between each 50lb bag. TL;DR: Good product & if you want a more sturdy base fill it with sand instead of water, especially if you're a guy and you don't want to have to pull your punches. If you're reading these reviews and you're worried about stability don't be, disregard people who filled the base with water and have complaints about movement so long as you're comfortable filling yours with sand you will get a far better result.

Love it feels great to hit thumbs up. 6 bags of 50lb sand bags makes this base very hard to move so think about that.

Everything good.

Nice Heavy bag for my baaement. Hangs on tight. Hit it with all I got and stand still. Will try out filling it with sand instead of water to make sure it stays straighter after strong blows (Front Kick, Side Kick and Hooks). Finally returning back to my roots! Love it!

So far so good. I've owned and used this product daily for about a month now. I mainly use this bag for practicing my muay thai technique, heavy bag routines, and to supplement/mix up my cardio routine. I filled the base with about 200 bags of sand, and it took about an hour to fill. One tip i can tell you, a gentlemen on Youtube found the perfect homemade funnel to help fill the bang with sand, a Simply Orange bottle with the bottom cut off. I can tell you this will hurry the process along than if you used a standard funnel for the job. I filled the base with sand because the base itself would move much more with water. To prevent movement, i also paired the bag with my pogamat exercise mat (made of a nice thick rubber), this really helps keep the bag where i want it. Now, this unit is great for my purposes. I'm 5'10, about 170. I don't crush the bag workout constantly with hay-makers (although it can take fair good hits mixed in with combos so far that i can tell). This bag is really good for speed drills, standard heavy bag routines, reasonably good for kicks (can't practice shin kicks, but you can practice fairly low kicks around quad level). This bag is not great for practicing knee strikes, although I can clinch the bag and lean it with my thick rubber mat keeping it in place, this would not work for a hardwood floor/carpet. I would definitely recommend this product for people below 5'11 who want to do some heavy bag work, or incorporate this into a cardio workout. For people about 6'-6'1'+ i would recommend the XXL or a larger bag.

This is a good bag for cardio and occasional big hits. It will move if hit with power but generally it stable. I like feel of this bag and adjusts easily. Tried medium light punching hold up well but heavy hitting or say a lunge kick would move it. Overall I'm pleased with this purchase.

I teach kickboxing classes and do one on one and this bag is perfect filled up. It’s heavy enough. It goes too many levels. It’s very sturdy and I have no doubt it will last me a very long time.

coups de pied, coups de poings, sans taper comme un dingue très bonne stabilité au sol, très lourd, une fois rempli d'eau.... cela fait du bruit, dans mon garage pas de problème.... un vrai plaisir de travailler sur le sac, cause covid et ma salle de sport fermée.....

Sehr gute Qualität, mit 100 kg Sand gefüllt sehr stabil. Meine Kinder (12, 15), die seit Jahren Fitness-Kickboxen betreiben, sind total zufrieden. Ich selbst boxe auch im Studio und kann dieses Produkt nur empfehlen.
