Best battery case?

[david61983]

What is a good battery case for the S6? I'm hoping to get one for less than $30 that hopefully doesn't add too much bulk.

Going cheap wont get you a good quality one. All battery cases add bulk.
I have a Mophie and its been great. Over the years with Samsung and HTC units i have tried other brands and always been let down by cheap battery cases.
You do tend to get what you pay for with them.
