Shoud your iPhone need a Case ? Those are prons and cons, let's discuss and share your opinions with 3uTools

Pros 

Safer: Do you need a case for your iPhone ? Yes, yes you do. Why? The rounded edges of the iPhones are slippery. It's hard to get a good grip on the new iPhones. Sure, they feel good in the hand, but if you add a little distraction to your day . . . You're going to drop your iPhone, plain and simple. At least, I'm pretty sure I will drop my iPhone 6 without a case. While you're at it, get a screen protector, too.

Individuality: There is another reason why I'm recommending cases to my iPhone. It looks fantastic and makes for truly astounding fit and finish, choose your own case which making your iPhone quite different with other iPhone users.

Cons

Hot: When you put your iPhone in a case, you iPhone will overheat and cause some dangerous problems especially when you charge for it. It is not a good choice to protect your iPhone hardware.

Heavy: A naked iPhone is thiner and that "luxurious feel in your hand" is wonderful, however it will be heavy, and un-portable. The need for cases is the iPhone's biggest flaw.

Whether or not to use a case is ultimately a decision only you can make. You are going to get answers from people who use cases, and those who do not, each telling you why they made their choice. What do you think of it?
