Wow where can I start?Its life size and adjustable. so you can simulate fighting someone taller or shorter then you. The base is huge, and when its full of water it makes this thing sturdy but it does give it a kick back so it feels real when you hit it. The body is dense and slightly squishy so it doesn't hurt when you hit it full impact with bare knuckles. When you kick it in the sides with round kicks it feels great, I love seeing the six pack so you can target perfectly right where the stomach is. And the best part, you can grab it by its head, pull it down and give it a good knee to the stomach, chest or head. I never had to do that to someone but man it makes you really imagine how good that must feel. You can do so much more with this thing then a normal punching bag. Punching it in the face just feels awesome. The best part is you don't have to mount it from the ceiling so it works great for being in a house.For those of you with anger issues, get one of these and tear it upIt took about 8 minutes to fill up with water using a garden hose. It's very realistic looking I am just amazed. The muscles, and face have some pretty freaky details.Negatives:Jumps around (moves) when you hit it hard so it requires you to have to move it back which gets distracting. I took a 3 foot board and set it on the floor between the base and the wall (wood panel around the floor/wall to stop this. Also what works well is grabbing it by the head while you're in beat it up mode and it moves back on its own magically.on another note:It will scare you or your friends coming in the house late at night. Looks like some mean buff dude is in your house. Might come in handy for Halloween ha.I love this thing, best work out ever, you can take out some aggression, practice your martial arts kicking/punching and body conditioning for you legs/feet and knuckles. I have never seen anything like it, best purchase i've made in a long time related to exercising.
