Of course, we will pay attention to a more comfortable sitting position, which is our original intention. We can put it in a studio, at home, in a conference room, in a booth, anywhere. He's a great Chan. To this end, our designers made more minor adjustments to the original M90C. When you have it, you will have more health.
