Perfection and great execution

Works perfectly!

Far more durably built than the other buoys I have used (3 other manufacturers). It is understandably heavier. The valves are more robust and positive in their closures than a simple twist valve. The dual bladder design builds for the resilience. it is excellent.The trade-offs are more weight & a protuberant valve that faces the water surface. Can definitely feel the difference in drag when underway. That said, if the drag from your buoy is a significant complaint, I would suggest that you have other, more substantial problems to address. :-)

very bright green-neon yellow, very visible. dual chamber for better safety should one chamber damage. solid clips for closing after rolling. roomy for keys / phone / snack etc. strap is long enough so it does not interfere with the swim strokes. clip looks strong and durable.
