“Effortless underwater fun and a nifty new device…for people who think swimming would be a whole lot more fun and relaxing if you didn’t actually have to swim... An extraordinary tool – I’d take it on holiday even if I wasn’t a serious diver because it’s just plain fun.”
Jonathan Margolis in How To Spend it
