Although they claim that this item can be used by adults, it is the furthest thing from the truth. You can only fill the black bottom HALF up with water, which you wouldn't know until you buy it. Due to this, you can't do any combonations with this bag as you knock on its' side with even the most mild of punches. Also, after a few hits, it rips open like your fists were made of nails even with gloves on.

The only reason why this purchase was made was due to the fact that I have no where to hang my actual heavybag in my apartment. This is not even remotely a replacment for a real bag. Save your twenty five dollars for something else. 1 star

We bought this for my 7yr old son, and in 2 days he had totally destroyed it. Thank goodness we had it on a tile floor. He kicked the bottom and it broke letting out all the water! What a mess. Not worth the money. 1 star

This bag is much better than the normal bop bags as far as rebound action.The old style falls all the down to the ground an then SLOWLY comes back to standing position.This one much more like a real bag snapping back and not hitting the ground unless you hit it to hard of coarse.My kid's are 4 and 5 years and only use the bag SUPERVISED being taught PROPER punching/elbow/knee and kicking strikes!I would never leave this bag alone with them to thrash on , it would break real quick and with a h20 base ,not good.GREAT FOR YOUNG KIDS TO LEARN ON....(NOT BEAT ON) the key is always, learn to strike GOOD then worry about how hard... 5 stars

The idea is great for my son who studies karate, but the quality of the product is below sub par. The pump broke two pumps into blowing the thing up. I spent the better part of the night hallucinating while blowing up this thing. Everyday it had to be blown up again WITHOUT THE PUMP! I told my son it was garbage and said he could practice on his big sister. DON'T cheap out with this. 1 star

My 8 yr old loves it! Have had no problems with it (except it does take quite awhile to fill w/ the little manual pump)! 4 stars
