ZooGoo

A friend of mine was browsing for a new case for his iPhone and came across a guy selling a few for $6 each on craigslist. Further investigation on google revealed that company who made these cases, ZooGoo, was giving the first 50,000 away for free. Being the Dutch kind of person I am, free sounded good to me (plus shipping, of course). Not only had my hard case cracked because of weak engineering, but I was in the mood to try a soft case. These cases feel like silicone, but don't attract the dirt and grime. They also come in an assortment of colors and I picked the one that I thought would accent against my black phone (I have a 4S). 

As you can see from the picture, it's minimal and has some ribbed edges for easy grip. You also notice a pen/stylus next to the case. It was also free (shipping, again). It's a decent pen and the stylus works well, though you'll probably want to use your fingers over that most of the time. 

Case Pros:
-Minimal and little extra pocket bulge

-Not sticky like a rubber or silicone case

Cons:
-Minimal shock absorption

-Hardly any drop protection

Pen/Stylus Pros:

-Handy when your fingers are wet, greasy, or lazy

-Two things in one

Cons:

-Not always picked up by my phone

-Can't replace two finger tasks
