True. But considering it’s going to be mounted on a helmet there are also available options for stabilization. I use my Wizard mounted on the helmet. To secure firmly the head strap I used velcro straps . Used 3 or 4 of these to make the head strap stay in the same place. Riding hard for 2 years and no issues so far. (although it probably works only for helmets with vent holes since you need to go thru with the velcro)
