Review on Polyform A-Series Marine Buoy by Rory Kelley

Used two A-3 size to keep my 10x30' houseboat from bashing our fixed pier. Easy to inflate with my compressor. Large surface area on impact seems to be much gentler on the boat's siding, not leaving any scuffs. So far they are working great and I see no reason why they won't last for many years to come.Edit: These are still good years later. Adding 2 more for more cushioning in our rough waters.
