Best iPhone Bumper Case / Best Battery Extender

[JayXL14]

Instead of making two different threads about this, I decided to just make one and see what happens..

1. What is the best eBay/"knockoff" Bumper for iPhone 4? There's lots of threads about it on here, but I don't know the best one.. Anything under $5/$10 let me know I'm sure there is one good one. Different colors are cool too, but black is important.

2. What is the best battery extender? Under $15 or $20 is cool.
(Not battery CASE, battery extender that you plug into the bottom of the iPhone 4 and charges it.)
- For this, eBay is not a good idea. I'd want something you guys reviewed or is made by an official good company.

Thanks

The bumpers discussed in this thread are awesome: https://forums.macrumors.com/threads/1049233/

I bought the red/black one, and it's just as good as the Apple Bumper. I ordered a white/black one and expect it any day.

These only cost $4.20.
