I use these chopsticks for 1 month.
We must recognize that there has sacrs differences between wood and carbon: these rods are a little heavier, the sound is a little diffrent but not unpleasant, strong, less bulbs in hands ...
I tried before a wooden models pack (like every drummer I think).
At the qualitprix report, worth given the service life of these sticks.

Now I pass carbon, no question of returning to the wood.
