Review on Polyform A Series Buoy: Durable And Dependable Marine Flotation Devices by Derrick Shaw

I purchased it for a zip line. I mistakenly purchased A1 size because I misread the description but ebay is letting me return it and replacing it with A2. For what it's worth, I think A1 size would be fine but wife is vetoing the idea because she'd afraid our kids will slip off.As for the product itself, it seems very heavy duty and well-made. The material is thick and took me a long time and a lot of effort to blow up by mouth. Not doing that again with the larger one. Since it's going to be used for a zip line and may be left outside in the sun, I wanted something that could do well with sun and water and what better than a ship bumper? Just get the right size for it.
