I use it for several months. I have a melodica Korean (melodihorn) and I tried to model the "fire" in the Hohner (model improved student actually). The thomann melodica sounds more "accordion" that precedent. I like her voice especially in the bass and treble (slightly less in the medium). His biggest problem is the evacuation of saliva. When you play a long time, it distorts or blocks certain notes. Suddenly, the stage use becomes dangerous! The quality / price is good but I plan to buy a melodica more pro! The Hammond 44 would do but it is too expensive. Maybe a "fire" in the Hohner pending ...
