This is as easy as it gets for taking clear photos and videos. I love the sleakness of the magnetic piece on my phone. No big covers or pieces to take on and off.
The eyepiece also serves as a protective cover when you pick up and move.
Installation was a breeze!!
Its fairly good at centering but may not be just quite up to snuff with some of its(self centering) competitors, but all in all I am a fan!
