Kapkur Anamorphic

I have only knew three anamorphic phone adapters until yesterday.  They are from Moondog labs, Beastgrip Pro and Moment.  Moondog labs should be the first one who made those and consistently stocked them,  with accessories like filter adapters no less.  Moment and Kapkur use a dedicated case for attaching the lens.  Moondog provides different models for different phones and a version with 37mm thread, and another with 12.5mm thread to attach to a phone case for newer phones.  Beastgrip provides a version with 37mm that attaches to the Beastgrip pro.  The question is which method provides the best alignment consistently, or does it matter.  I tend to think the custom case provides the best attachment and alignment consistently.  Once the phone is dressed in the case you just need to screw on the anamorphic adapter, i.e. the lens.  There is no guesswork to any vertical or horizontal alignment to play with.

I was at the PhotoPlus Expo yesterday and I was pleasantly surprised to see Kapkur offers anamorphic adapter.  I tried it on for 8 seconds.  I guess it's not bad.

I have no reference of course and I am surprised there isn't any comparison out there among these four adapters.

With phones coming out with twin cameras and whatnot, it seems there is a trend to make a dedicated phone case to attach the lens.  And then in turn, one could just shoot like so or mount the whole setup onto another rig like a Beastgrip to further add shooting features to the setup.
