Are cheap Amazon standing desks actually stable?

Reddit threads on r/StandingDesk and r/StandingDesks are mixed: single-motor budget desks like FEZIBO and ErGear are widely reported as stable at sitting height but show noticeable wobble at full extension, especially with monitor arms. Dual-motor and heavier-gauge frames (VIVO 60-inch, DeskShow double-beam) get better stability marks.
