This bag will do everything that I need it to do. That said, I do not see this bag as a replacement for a traditional heavy bag. I'm using it as a strikable weight to hang from the bottom of a bungee mounted Virtec HAWK training dummy torso (like a BOB but with manipulable arms). The most obvious deficiency in using this ball shape in place of a heavy bag is its small size. There is absolutely no way that you could work low/high combinations. You are basically working against an absurdly oversized head. This may be fine for "cardio" boxing type training, but it is useless for actual combination training, and it is beyond useless for any type of kickboxing or other martial art that uses the whole body. Other reviewers have said that the bag is surprisingly hard, I have to agree with that. This ball when full of water gives impact resistance similar to a high quality sand-filled leather heavy bag. This is not a con in my opinion, but if you are accustomed to a soft foam bag like a wave master or similar you will likely be unpleasantly surprised. I would definitely not recommend hitting one of these bare handed, at least not for an entire workout once, once or twice while walking past it shouldn't be a problem. Lastly, you should expect to make a mess filling this thing up. The hose nozzle that is supplied with the bag has no on/off valve. This means that you will need to either have someone standing outside next to the hose faucet (you can only fill it with a garden hose) or run back and forth turning the water on and off. Neither solution is ideal. I actually rigged a valve in between the hose and the nozzle and still spilled at least a quart of water. Overall, it is a good product but of very limited use in a gym and not versatile enough to be the only piece of equipment in your garage.

A great product! I use this exact bag in the boxing studio I have a membership at but wanted more flexibility to do it at home. I loved that there was an air inflation option that's part of the water plug to get out any wrinkles. It's a beautiful sight in my garage and I know it'll stand up to the beating!

My 185 pound fiancé works out everyday and uses this in his workout and he loves it

Bag cracked and starterd to leak water

This is a good product,only one thing I don't like is the water plug is hard to put it back in after filled it with water.It leaks every time I hit it.Still will recommend this product.
