First of all folks, you will not get what is advertised in the picture. The pictures give the overall impression that the design of the bag is very robust, this is not the case. The bag seems to be stitched very poorly and after a few sessions, a portion of the stitching completely ripped open. This bag is advertised as heavy duty, I suppose the definition of heavy duty is highly subjective, if you weigh less than 6 or 7 stones, then this bag will do a very good job for you, but if you're heavier than that and you want to practice more that once a week, its likely that you will rip this bag to shreds in no time whatsoever. As the headline states "You get what you pay for," if you just want a play thing for the kids, then this bag is perfect, but if you want a bag that can stand a beating this is not the one for you, save yourself the hassle of a return and save up for a bit longer and get a propper bag, one thats a bit stronger than wet paper mache.
