It is my first chromatic, and I use it for learning and playin at home
It took some blowing time to warm up reeds for the lowest notes, but now those registers work perfectly even if lightly breathed.
Overall it has good tembral qualities, and pleasant tonal balance. Sliding bar works smoothly and silently.
I certainly would recommend this product. But keep in mind, that it could take some time and patience to make this baby sing its whole diapason for the first time. So do not take it directly from the post office straight to the gig. But after taming it, it will work perfectly even if unused for monts.
If not those 'curing hours' at the very beginning, I would give all 5 stars. But as I mentioned, I am not a pro, so maybe that 'curing time' is just a norm for any harp.
