Questions about Contini Height adjustable office desk

Has anyone else had the glass table part of the Contini Height adjustable office desk spontaneously break? The glass shards went everywhere - super dangerous and probably in hindsight not worth it.

i can no longer adjust my table and have unfortunately lost the operating instructions... whenever i press a button, bot or loc appears and the table doesn't move. which button combination do i have to click again to get out of this loc mode? plugging in/unplugging has not helped

Hello, is there anything planned for cable management? Is it possible to neatly store all the cables (screens, charger, etc)? Thanks

Does the black table really have a glass top? This question has already been asked but has received two different answers: One user said "glass" (which makes an optical mouse not work), another talked about "chipboard with coating" (unclear but made of what material, maybe plastic?).

What is the wattage of the USB ports?

In the photo, this table has a cross-brace at the bottom so that you can hardly stretch out your feet. It is missing on the YouTube videos. So does it need it? And is the tabletop made of wood, i.e. can it be drilled through, e.g. for a monitor holder or cable entry? Thank you very much.
