Query: worst buy I have made in years!!!!!

I bought this to go along with my Everlast 80lb bag and it was the biggest mistake I have ever made. Number one the first and biggest problem is that it doesn't come with the F***** lag bolts that you need to mount the thing to a brick wall.The directions are very poor and automatically assume your mounting it to a wooden wall. I mean really how many people have wood walls in their basement? Number two the speed bag platform is made from particle board, and the swivel is made of 95% plastic. The bag itself comes deflated, and doesn't come with a needle to pump it up. The metal framing is cheap, and doesn't hold together right, The holes to mount it up on the wall on the metal framing are absurdly small 5/16 of an inch. So basically your paying $45 for a set of hand wraps, a jump rope, and bag gloves. I would not buy this unless you want the f*****g thing falling out of the wall and onto your head.
