These desks are designed to stop if the force increases an unexpected Amount (say, getting caught on something). Also, the moving parts are all hidden - so long as you are far enough away from (say) another desk tou should be okay.

But you can still accidentally yank a phone or laptop off the desk without tripping the sensor if the power cable is too short.

The permanent cable management will obviously be fine, but "I just need to charge my phone from that outlet in the corner for a few hours, I'll definitely remember to unplug it before I raise the desk" is the kind of thinking that inevitably leads to shattered screens.
