This is a really excellent product—I ordered it from China, and the craftsmanship is incredibly detailed and high-quality. It’s well worth the price, especially since the price isn’t excessively high. I haven’t tried it out yet, but the quality of the product itself is outstanding. The delivery was prompt, and the brass finish feels just right—comfortable in the hand. I’ll give it a try soon to see how great it really is. It’s quite different from the Japanese brand, which costs about four times as much—it would be way overpriced for that kind of money.
