Oh god yes it's a decent phone. It's far more than just decent. It's the best one I've used recently, and I've been using the S7 edge, iPhone 7 Plus (sold that), and Pixel XL (returned).
Yes, it does have shatter proof glass, although I'd get a screen protector because the shattershield scratches more easily.
Yes, the Incipio Performance case (Level 4) is great for durability and pocketability. Don't buy it at a Verizon store, though. Get it on Amazon for half the price.
Battery life is amazing, especially when you add the battery mod to the phone! Get the wireless charging battery mod so you can, uh, charge it wirelessly. I put the battery mod on my phone this morning when both the phone and mod were at 100%, and the power on the phone is at 100% while the battery mod is at 52%, with about an hour of screen on time.
Camera quality is amazing, just one point behind the S7 edge in the DxOMark scores (87 for the Z Force Droid vs 88 for the S7 edge)!
