Review on Polyform A-Series Marine Buoy by Abdulkarim Sugge

I bought A-3 to use as a heavy bag and I absolutely love it. The key is to find a nozzle/tip that can fit into the air valve, otherwise you will not be able fill the buoy with water. I am 6'3', about 260 pounds, and have been boxing for about 8 months. I can unload on this bag and it takes it like a champ. Do not fill it so it is rock solid (unless you are some absolute machine of a boxer) otherwise you will get pretty sore.
