I worried the punching bag for my son for Christmas. Amazon was known to be very good and fast. The ball and the gloves are useful in any case, but I am not a professional. After installation we tried the ball and everything was OK. The next day, the punching bag has fallen down (without content in the foot) and the rod holder is broken (it was so knocked over no striking the ball). This bracket is only made of plastic and the rods do not go into each other, so that the entire load of the side affects to this plastic holder. I have not exchanged the device because it is in my opinion not worth it. I would again get the same poor holder. This rod holder is a bad design. Instead, I have my own bracket attached.
