The Victorinox Swiss Army Jetsetter looks like a traditional pocket knife the company is famous for, but instead of the knife you get a pocket full of storage.

A foldout and detachable USB 2.0 flash drive is among the features in the mini tool kit, which includes a ball point pen, bottle opener, Phillips screwdriver, tweezers and scissors in the 16 GB model I tested out.

The detachable flash drive is Windows- and Mac-friendly, although it comes loaded with Mac-friendly security software to protect your data stored on the device.

It’s available in capacities of 8 GB black ($39.95), 16 GB red ($49.99) and 32 GB silver ($99.99). There are a few different features in each, with the 32 GB model having a LED mini light, for example.

A great find

Kensington’s Proximo Fob and Tag Kit creates a wireless (Bluetooth) monitoring system between your keys, accessories and an iPhone (4S or 5) that will alert you if they are separated.

I tried the starter kit ($59.99), which includes a fob, tag, keyring and has a screen driver to open the hardware and insert the included CR2032 lithium coin batteries, along with a key ring.

The fob attaches to the key ring and after you have it linked with the free Kensington Proximo app, anytime the devices are separated an alarm sounds. If your phone is within range but you can’t find it, press a button.

It’s easy to think of this as a monitoring device for your expensive smartphone but it also works in reverse once everything is linked up. With your phone in your pocket or purse, it can alert you that you have left your keys behind.

can be placed in a computer bag or attached to anything (or anyone) that you want alarmed. But unlike the fob, it’s only one direction; the app will find it but you can’t use it to find your phone.

The Proximo App Dashboard tracks up to five items with a single fob and up to four tags. Additional tags cost $24.99 each.

If you get out of range between the devices, an app lets you tap a button to let you know where your device was last seen and even pulls up a map with a specific address.

Sound investment

RadioShack’s Auvio expanding Bluetooth speaker ($39.99) is as simple and useful as a gadget can be. Just twist open the speaker, pair it with your device via Bluetooth and you’ll be amazed at how much better the sound is than the built-in speaker on your smartphone or tablet.

A rechargeable battery is built in for up to eight hours of use and can be powered up in two hours with a USB charge using the included cable.

It is 2.5 inches in diameter, just over 3-inches tall when expanded and about 2.5 inches when closed.

Another choice, with a bigger size (2.8-by-6.5-by-2.9 inches) but much better sound is the brick-shaped Auvio Portable Speaker ($79.99).

Both speakers have aux-in ports to connect to non-Bluetooth devices.
