Idea is great, unfortunately for my purposes ungeignet

I wanted to Steelie use to create a mount in the car with my Xperia Z2.
The magnet and the adhesive holding super. I glued the ball joint on a smooth plastic surface and the small magnet on a Broit holder.
The adhesive bond maintains perfect!
The magnetic connection is super.
What I unfortunately have to complain about, is that the weight of the Z2's and its holder
are seemingly too large and thus constantly adjusted the angle.
The adhesive can be removed without leaving any residue with a piece of fishing line and be patient.
I think the Steelie is perfect to fix things easier, or where the angles need not necessarily be given.
