Piano-Net is easy to assemble, reaches over the entire grand piano and helps catch dropped items. Every grand piano should have one.
The action and keyboard are vital parts that must be whole and adjusted to work. When exposed, it is easy for foreign objects such as pens and paper clips, etc. to fall into the mechanics and in the worst case destroy parts. It can be seen as unnecessary and above all costly as a piano technician has to be hired every time to remove the lost one.
