No problem with red release button as dasnowman experiences. Not removing and replacing the front wheel is a big bonus.
Gave one of my HighRollers to my daughter who has a 2-dr Accent so the tray cantilevers significantly off the back crossarm. Note the weight (>21 lb) compared to the King Cobra (>12 lb), which gives the rigidity for the cantilever but may be unnecessary for normal installations.
