Very good

The top-quality product has excellent sound.

The support appears to be of excellent quality. It includes sanding materials, a handlebar, and torso plastics, all carefully packaged. The support can rotate to predetermined angles, and the threading, which is often a weak point in these types of supports, seems durable.

The quality is very good. To prevent vibration, just tighten the small screw located inside. It's also impeccable.
