Practical aluminium protection for the iPhone
The New York Times
ALUMINIUM cases for the iPhone tend to be light and durable but are assembled with minuscule screws that are easy to lose or snap.
The AL13 aluminium case from Designed by M avoids that problem by using a sliding frame to lock the iPhone into place.
The AL13, which began as a Kickstarter project, is a bumper-style case. That means the hard part wraps around the edge of the phone, and leaves the front and back unobstructed, like the plastic bumper that Apple supplied with the iPhone 4.
The AL13 case comes with a protective film for the front and back of the phone.
The case is very easy to assemble. After you apply the films, you just slide the rear frame off the bumper. It glides along a track like a drawer. Push the phone into the bumper then slide the frame back into place (which can take a little fiddling).
It looks like good protection against scratches and dents, but because there is minimal shock-absorbing material inside the bumper, I wonder how much protection there would be against the concussion of a drop.
The bumper, which is of anodised aircraft aluminium, is made in purple, blue, fuchsia, white and gun-metal grey.
The AL13 is available online from Designed by M, at US$80 (S$100) for the iPhone 4 or 5.
