      Comments about InCase iPhone 4 Black Snap Battery Case:

      Product fits great on my iPhone 4 and extends the battery life about 40% more. Had an older charge case and it was really bulky. It charged a bit more than the inCase, but I really didn't like walking around with something that looked like a brick.

      One thing to be careful with on the inCase is getting sun tan lotion on it. The film on the outside of the case can potentially start to crack if you get too much lotion on it. Other than that, I really like this case.

      I'm not using it as an everyday case, but will put it on when I know I'm not going to be near a charger during the day. With the inCase on, I can go the entire day and night on my iPhone without charging- something I could never do before.
