This fits perfectly to the iPhone 5 and its purpose: to damage protection from drops and shocks from the side without the cell phone. Especially the last point, this solution is better than achieved with other suppliers. In addition to the basic requirement of protection against falling dirt or dust hardly find the way between bumper and iPhone, which is particularly important in the black version, so as not to scratch the aluminum antenna.
Openings for charging cable and earphones are also fine
A deduction is available for the low-grade solution of the volume control buttons and the on / off switch. This should / could go even better.
In total solid and definitely above average, especially for the price.
For this one last note: for 1.99 you can in my opinion not a product expected to last forever. My Bumper of this kind keep an average of about 9-12 months - then the rubber is worn out, because you repeatedly abmacht remove the envelope so to the few but the dust finds its way inside.
