Review on Polyform A Series Buoy: Durable And Dependable Marine Flotation Devices by Darren Pham

I wrote a detailed review but for some reason it was rejected by ebay. I'll try again though. I purchased the A-2 size buoy. It's most similar to the the 15" Aqua Fitness bag.It was pretty easy to fill. The ID (inside diameter) of the fill hole is 1/2 inch. I had some 1/2 OD tube that fit snugly to it. I connected that with an adapter to my sink and filled it up in less than a minute. The max I could get it was about 65 pounds, however the buoy had no give so I let some water out. I was happy at around 58-60 lbs.I used my old heavy bag set up , hung between 2 beams, with a 90lb spring an some carabiners . The thickness of plastic at the hole where you would connect a anchor shackle was 1.4 inches. I'd need to buy a 7/8 inch anchor shackle for that to work and didn't feel like spending another $20 dollars. I just went with a 5" carabiner from home depot that is rated to 120 lbs.So after using it I'm pretty happy with the results. It does swing a little but the next option was the A-3 18" model. And trying to hang 120lb bag seemed like ti would be alot of trouble. Plus the A-3 were $60 and the A-2 were going for $30.Can't imagine how an Aqua bag would be much better, I'm very pleased with the purchase for $30.
