Miggo Pictar OnePlus Mark II - Apple and Android Smartphone Camera Accessory | Turn Smartphone into DSLR | 5 Buttons for Function Control | Compatible with Pictar App – Black

The physical product is fabulous, the look and feel of the ‘sleeve’ is very professional and strong. The only problem is the item must be used with its own App- this needs much more work.It’s not very responsive and crashes all the time. Unless this gets some major updates and bug fixes, I’m afraid to say that you’d be better off using the phones’ camera alone
