Thanks, that is really helpful, and good to know that sometimes we can still trust A-brandanufacturers for producing higher quality stuff. (Unfortunately, there are many examples nowadays of manifacturers who simply put their brand name on a generic product and raise the price. My brandless melodica even has an empty plate where a manufacturer can put its brand name…)
In this case, the melodicas were SO similar that perhaps the same mould was used but with different materials and internals.
Anyway, I may try the Pianica from Yamaha now 🙂
