I was recommended to buy one out of three models on the key of C to start learning this amazing and portable instrument. Please take this review with a grain of salt, because I am no pro and cannot really compare since this is the only one I have, but truth be told... after 4 years of having it, I think it sounds better than the first day, ok I got better at it, I was the one making it sound bad at the beginning haha.
Still, it's response it quite satisfying, not much air is needed to get a note.
Take it anywhere, but airport security will want to check it 9/10 times.
Spending just a bit more feels now after 4 years like it was worth it, my second harp is also from this model, although I wanted to try Marineband I was conservative and decided for what I am used to.
