I bought this MP off Ebay just out of curiosity. I looks like a copy of either a Rovner Deep V, or a Jody Jazz DV. I really wasnt expecting much more than a good laugh for the $37.90 I spent for it, including shipping. Was I wrong. This mp has perfect intonation. Is not reed picky. And plays wonderfully. At less than 10% of the cost of a DV, it plays at least 75% as good as a DV. I have been playing it all day and out of dozens of mouthpieces I have bought in my lifetime, this is by far the best bang for the buck. Once in a while you just have to take a chance. It paid off.
