We have had an Airhead Composting Toilet on our sailboat for over 2 years now, and I can say with much emphasis that we still consider it in the top three items we’ve put on the boat for ease of comfort, simplicity, reliability, and complying with waste laws, which makes it a huge plus for not ever worrying about ANY destination we travel to. Having just recently had to completely re-build a family member’s toilet system (not an Airhead), I can once again say: “I never ever want to be without an Airhead on a boat that I live on!”
