hasn't had any air chamber leaks. I did replace the air floor after about 10 years, and the new model seems a bit sturdier. I also spent $10 for one part hypalon cement to reglue the rub rail. Otherwise has been trouble free. I also have 30+ years experience with Avon, and still keep a Redcrest about that old for trips where I just want a small shore dinghy and no motor. So I plan to stick with Avon.
