Are the iPhone 6 liquid cases protective?

I have an iPhone 6 with a glass screen protector. I was wondering if my phone would be okay if I dropped my phone with the liquid case if I had the glass screen protector on? I really want to get one but it's not worth it if my phone will crack. (the liquid case are those cool bulky cases with the glitter moving with water inside)

No phone case or screen protector can protect your phone from damage in all circumstances. Sure, they help, but none are perfect.

I wouldn't recommend it.
