Now they are finally up! A tip from the coach, if you're going to put them up, always start with the bottom one and work your way up. Be careful, otherwise some paint might peel off the wall (might have happened here)
It also says in the description that you have to start from the bottom (because they need to be clicked in and for that requires some height from above). There is a pretty clear picture in the instructions that you start from the bottom and that there must be x number of centimeters from the ceiling (for the same reason, they need to be clicked into the rail). 😊
