The Galaxy Note 4 is not cheap and should be reasonably protected.
The case is stable, to get to all the openings and is good grip.
From one or the other has been reported that the built-in screen protector shimmering rainbow colors. That's true, but that is very pending of how the lighting is and from what angle you look at the display. Though I often used my professional Smarty, I was not even affected this.
The case is of high quality and absolutely worth the money. In the "long-term test," but I am curious to see how long does the rubber tabs for the connection cable, the S-Pen and the headphone jack. So far, everything is super.
