Just received this from eBay. A Chinese made Baoer 500 with gold plated Medium nib. I like the weight of the pen: not too light and not too heavy. It came with Baoer's own piston converter. Filling it with Private Reserve Daphne Blue ink, it writes very smooth and wet. Even though it has a MEDIUM nib, but it looks like the BROAD nib of my Pilot Vanishing Point fountain pen. The Baoer 500 is a very good pen. I like it.
