I have a Luvvitt Clearview for my 6S Plus. The power button and volume buttons are pretty stiff, squishy. The clicky feedback comes through, but they are definitely not as they should be. My old Luvvitt Clearview for my 6 has fantastic button action. So I'm looking for something similar, like the Spigen Ultra Hybrid, though I'm unsure of button action on that case. I definitely like TPU on the sides and the hard poly on the back. I find it ideal for grip. Any suggestions?
