I love this series of cases. The feel in the hand is good and the raised squares on the back allow for a good, non-slip grip.
I have owned 1x blue one and 2x read ones for use on my Note 4.
Why so many?
Because the case has a construction flaw.
The case has an inner section in contact with the phone - this part is fine.
Then there is an outer section which provides the textured back, which is wrapped over the inner section.
Unfortunately, this outer layer is made of a quite brittle plastic. It takes only minor impacts to chip off parts of the corners or even bits of the sides of this outer layer.
Eventually, the outer textured layer of the case falls off because it is not glued on - only held on by the clamping effect of the clip-shaped corners and curved side segments.

SUCH A SHAME. I love the look and feel of this series of cases so much that I have bought 3 of them in succession as each previous one has broken down.
But sorry - I will do so no more.
If only the manufacturer would use a less brittle plastic for the outer skin, they would have a real winner.
So 10 out of 10 for case design and look and feel.
Only 5 out of 10 for choice of construction materials.
