The KOALA is exactly what I had hoped for. I purchased several for skiing/riding/snowshoeing friends, and I would purchase again.
The product’s design is flexible and fits many (most?) devices and their various connections and camera configurations.
One corner sometimes rolls off when wrangling phone from jacket pockets (especially when using gloved hands on the lift), but sticky silicon helps to keep phone secure.
The clip works best when fastened around a bump in material (e.g., zipper, draw-cord, seam, hem, etc…)
Test anchor point(s) before adventuring; a closed clip may still slide off of thin or slick material when pulled. I clipped around the top teeth of an outer breast pocket zipper because the inner material of the pocket was too slippery.

PROS:
Clip is very secure once fastened.
Silicon grips phone well.

CONS:
Clip does not hold well on some thin or slippery materials. (Add silicon to the clip’s teeth perhaps?)
Corner(s) can roll off device during removal from garment pockets.
