Cool clave. But for every plus, I found a minus for myself. Pros: 1. Very quiet switches. Quieter than all membranes in my house. 2. Convenient hand support. 3. Very convenient wheel with the ability to turn off the sound by pressing. 4. Very comfortable and beautiful lighting. Has cons: 1. Switches are very wadded. Feeling as if syrup had been spilled on the clave. 2. Backlight under the arm is not attached to the clave, but placed under it. 3. The volume wheel is very loud and difficult to press. It is very difficult to turn off the sound and not turn the wheel. 4. The software for setting the backlight is very incomprehensible. So I could not figure it out, but there are no guides.
