Pros: A two-piece case made from durable and protective machined aluminum. Industrial looks, sealed with a super easy magnetic closure. Compatible with both the first and second-generation nanos.
Cons: Shows minor scratches on the aluminum surface. Available in only one color, sliver. Bulks up nano to the size of an iPod mini.

An update to the iLounge reader-favorite series of machined aluminum iVault cases for iPod shuffles, Griffin’s iVault for nano ($25, aka iVault nano) is long in coming: we’d heard a first-generation nano version was on track for release last year, but as it emerges in April, 2007, it’s now compatible with both first- and second-generation nanos. Unlike its predecessor, the new iVault uses magnets rather than screws to hold closed, and includes a convenient rubber Dock Connector cover — which fits the second-gen nano better than the first — to protect your nano’s accessory port.
Integrated clear screen and Click Wheel protectors are also found in the front half of the case, with a rubber inner lining to keep your nano from scratching against the aluminum body.
In an update to the iLounge reader-favorite series of machined aluminum iVault cases for iPod shuffle, Griffin has just released iVault for the nano ($25, aka iVault nano). Combining safety and security, iVault is an aluminum brick of a case that’s actually compatible with both first and second-generation nanos.
The new iVault has the same general two-part design as its shuffle predecessor, with substantial-feeling carved metal pieces serving as front and rear shells. But now iVault uses magnets rather than screws to hold the shells together. This is a fantastic and convenient improvement, which we really liked; finally, we can save the screwdrivers for Sunday brunch. But as before, the machined aluminum design requires a compromise: iVault nano mirrors the size and dimensions of the discontinued iPod mini, giving your slim nano a bulkier and heavier feel. As the photos show, it adds millimeters to a nano’s top and bottom, and more to its sides.
Ease of use is generally impressive: you get access to the nano’s screen, Click Wheel, Hold switch, and bottom ports. While iVault does not interfere with most Dock Connector cables and headphone plugs, especially large headphone plugs and cables may have issues, and docking the iVault with most speaker systems will prove difficult. We found it best to remove the nano from the iVault completely before docking with another device, which is now easier than in the prior iVault thanks to the magnets.
As the vault name implies protection, it’s no surprise that this case scores nearly perfectly in that category. Although you should not duplicate our testing methods at home, the iVault can withstand being dropped, tossed and even stepped on. Integrated clear screen and Click Wheel protectors are found in the front half of the case, while a rubber Dock Connector cover, which fits the second-generation nano better than the first, provides additional protection. Although most users will not mind this, it should be noted that the headphone port and Hold switch are left exposed, lowering the Protectiveness score to 9. That aside, those parts of the nano that are covered feel well protected.
Although not completely scratch resistant, the iVault does have a strong outer aluminum shell, while the interior is cushioned with a soft rubber inner lining to keep your nano from scratching against the aluminum body –- a well thought out and executed design.
