Great harp all around! I already ordered another.

I ordered the JDR Ninja in Eb to try it out in a key I didn't already have and it's great! I ended up ordering another in C to more directly compare to other harps I've played and I'm expecting good things. It's super comfortable in hand and is a bit bigger and heavier than some of my others but in a good way. I'd say the air flow is a bit more restricted than some of my Hohner Special 20s, but that might be the key, and it isn't bad at all. Easy to bend, good tone, loud, overall I couldn't be happier with it.
