Z&J is a Chinese Sports Brand that makes Several different types of Paddles. I bought a pair of wing paddles to try them out, and I have to admit that they are every bit as good as an Epic wing Paddle, but with a much lower price point. There is nothing you'll be left wishing it had (perhaps a prettier logo, but that's about it).
The feel of the paddle stroke, weight on your hand, and material quality, everything feels top notch with this paddle.
If you are planning to paddle long distances, then it is best to buy the small/mid sized paddle. For sprinting, you can go with the large paddle if you are strong enough.
