My purchase was 9 meters long.
Objectively, in order for it to work, it requires height as it is difficult to let the line go, but also difficult to lift heavy fish out of the water due to its flexibility. The negative factor is its weight, and the positive factor is perhaps its high parabolic shape in the front sections. I struggled to lift a nearly one-kilogram fish and an 800-gram carp, as the rod did not easily come out due to its flexibility (compared to a 7-meter one, for example), but in the end, it provided me with great excitement this summer.
The key is to play around with the height of the rigging depending on the spot in order to make it work.
