I'm not sure of the details as I received this item from someone else, but I believe it's likely a JMICHEAL. While it's inferior compared to the big three manufacturers, I've only used it for practice. The pitch tends to fluctuate easily with the rise and fall of the notes, but it shouldn't be a problem for those who can adjust with their embouchure, etc. In my opinion, the resistance is low, and the response feels good. Also, compared to the lower-end models of the same manufacturer, I feel it's much easier to produce sound. (I get the impression it's probably a higher-end model.) I've had it balanced once, so I'm setting the price accordingly. Please note that this is a used item, and no claims or returns will be accepted.
