Review on ⚓️ BTG GEAR Two: Premium 15"x20" Red Boat Mooring Buoys - Round Inflatable Balls for Docking, Fishing, Crabbing, and More! by Richard Gross

These are great round inflatable buoys for mooring. They will be filled with air but shipped empty. Access is a plug that unscrews from the air fill port. It's almost impossible to fill with a hand or foot pump because you can't control the pump and hold the fill tube into the port with enough force to keep it from popping out. Using a pressurized tank it was easy to fill these buoys but they must have a tip that fits into the fill hole and blocks the port sufficiently to prevent air from escaping around the pressurized tank tube. This accessory is not available. After filling, the buoys work great. They are well made and of solid thickness and should provide years of service.
