I have used these china cheapos off ebay for my Note 4 & S3 and wifes S4.
The last one I got in October works fine on the Note 4 and its slim as hell.
(sorry cant post links yet bc Im new here so - )
Do ebay search for:
"For Samsung Galaxy Note 4 Hard Crystal Clear Hybrid Soft TPU Bumper Case Cover "
from seller "auto-enterprise"
We've dropped all of them and it prevented breaking. Edges are soft and rubbery and good gripping. Its raised just enough to keep glass face off of flat surface.
The rubber starts to pull apart from the plastic edging after a few months, so they are disposable.
I usually buy 4 at a time in different colors.
