Smartphone mount

Does anyone have a better idea ?

I use a monopod which has a 360 degree camera at the top, but I also have a smartphone mount halfway down.

With “SmallRig Super Clamp with Ball Head Cold Shoe Mount - 1125”

Which works ok. It’s a bit heavy. Holds very securely though.
The smartphone grip clamp actually feels like it could grip hard enough to damage a phone if you tighten the screw too much!

So I bought it and I am very happy with it. I should have bought it a long time ago.

With my Cullmann sucker, I am not so happy.

This is no more in production. It has a very short (or no) arm at all. I like that = less vibration.
But they don’t tell the minimum angle.
I also think it is not possible to tighten the quarter inch screw itself.

Some people just do not want to sell. Is there an alternative ?

Or there is the more flexible long armed
