I bought an Airboard 32. It’s has a fun look but is not really different than most other melodicas. The yellow, bendable mouthpiece that seems to be made from parts that were designed for some other (possibly plumbing) use. It has a black plastic gasket that is a little too tight. The gasket on mine got damage after using it only a couple of times. Without the gasket, the mouthpiece won’t stay attached to the melodica. (The mouthpiece has threads, but corresponding opening in the melodica does not.) I took the damaged gasket off and wrapped the threads of the mouthpiece with a lot of teflon tape. That works okay.
