Very good price and very good quality for a “chinese” rod !it have the same or better specification than other rods that is more expensive
These feel just like rods that are double the price. They were all exactly the same size, length, and weight! Very balanced and very happy! They run smooth and I’m confident they will hold good power. Don’t worry about the China reviews you see online, these are awesome!
