Do the iPhone hard cases actually protect?

Do the iPhone hard cases actually protect?

From external scratch, yeah they protect. However they don't protect from the impact from a fall.

From external scratchs yeah. But with a beveled edge maybe a tad bit. It's better than nothing. But I have shattered two iPhones. The 4 and 5. They shatter easy no matter what case you have on. I would recommend an otter box or life prof. Or a balistics case. I use Amazon bc they are always good prices on there.
