A decent quality harmonica, based off of popular designs, not trying to reinvent the wheel. Fairly airtight and there's no air leakage between the two positions. The button does occasionally feel a bit sluggish, but it's nothing that impedes playing. Also, could maybe be a bit more responsive in the high registers.
Has quite a reliable feel to it. It certainly does not feel as if anything will break anytime soon. Also has a good weight to it and sits relatively well in the hands. Maybe not as comfortable as something a bit more rounded; has some sharp edges. Again, nothing to really impede playing.
Overall, great harmonica given the price, and certainly amazing for a beginner.
