This is harder rubber, fits tighter, and is really a nice case.

One distinct improvement over previous generations is the rubber is not as "sticky," and is therefore much easier to get in and out of a pocket

the rubber broke off

The outside rubber is rigid enough for it not to move around a lot.

I have bought many similar products like this for a less money, but they just don't hold up like the otterbox does and the rubber feels cheap.

I can see that bottom rubber under the hold button becoming loose in some

My last one lasted two years replaced it because it got grimy and nasty and the oil and grease started deteriorating the rubber outside of the case.

Softer rubber like material over the plastic

This rubber is much more user-friendly without compromising adhesion on slippery surfaces (like a car dash).

Much better than the iPhone 4/4s cases where the rubber was too soft and pulled away from the hard plastic case underneath.
