Title says it all really, very fun to punch and kick on and for accuracy training nothing can top it, but needs tons of sand to withstand hits without falling over, if you have decent punching power like myself. I've had to put about 75 lbs more sand then manufacturer says to, I'm lucky all of that sand fit in the base, but like some others have said you can also use small rocks, pebbles along with sand to weigh it down. Do not use water, won't be heavy enough unless your a total wuss. Would have given it 5 stars if base was weighted to begin with, in other words some sort of metal instead of plastic but that would drive up costs, so I understand but also they should have made the head and face a little less soft, a bit harder and it would be perfect. Also, if your interested in buying one don't listen to the people that say BOB cannot replace a heavy bag, it most certainly can coming from someone who has used 100+ pound heavy bags for several years, I prefer the BOB hands down and haven't bothered with my heavy bags since, although part of that is due to limited space, which is another win for BOB. Its obviously realistic & helps improve accuracy compared to a heavy bag. If you got the money, and you like to punch and kick things and/or people, BUY IT. Had it for 6 months now and it is holding up perfectly so far.
