Kensington's Proximo Fob and Tag Kit creates a wireless (Bluetooth) monitoring system between your keys and 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 and key ring and has a screwdriver to open the hardware and insert the included CR2032 lithium coin batteries.The fob attaches to the key ring. After you have it linked with the free Kensington Proximo app (a very easy setup), an alarm will sound anytime the devices are separated. If your phone is within range but you can't seem to find it, press a button and it will ring.It's easy to think of this as a monitoring device for your expensive smartphone, but it also works in reverse. With your phone in your pocket or purse, it can alert you that you have left your keys behind.Within the app, you can set the sensitivity and a specific sound to allow you to control how far you're separated from your device before the alarm goes off.The tags look like the fob and can be placed in a computer bag or attached to anything (or anyone) that you want to set an alarm for. But unlike the fob, it's only in 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 one fob and up to four tags. Additional tags cost $24.99 each.A battery meter on the dashboard will alert you of a low battery needing replacement in any of the devices, which should be about every six months.If somehow 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.Even if your phone is on silent mode, when the alarm is activated, you'll hear it.www.kensington.comMore soundRadioShack's Auvio expanding Bluetooth speaker ($39.99) is a simple gadget, but it's one you won't stop using.Just twist open the speaker, pair it with your device via Bluetooth and the sound is improved over the built-in speaker on your smartphone or tablet.It's not room-filling sound but great for an office or having some sound to play satellite radio while stuck in a hotel room.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 long 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 the brick-shaped Auvio Portable Speaker ($79.99).It's also Bluetooth, works as a hands-free speaker phone and runs on a built-in rechargeable battery.Both speakers have aux-in ports to connect to non-Bluetooth devices.www.radioshack.comPocket toolsThe Victorinox Swiss Army Jetsetter looks like the tradition pocketknife but instead you get a pocket full of storage.A fold-out, detachable USB 2.0 flash drive is among the features in the mini tool kit, which includes a ballpoint pen, bottle opener, Phillips screwdriver, tweezers and scissors in the 16-gigabyte model I tested.The detachable flash drive is Windows- and Mac-friendly, and it comes loaded with Mac-friendly security software to protect data stored on the device.This lets you secure your data with passwords without leaving any cookies or history behind.It's available in capacities of 8GB black ($39.95), 16GB red ($49.99) and 32GB silver ($99.99). There are a few different features in each, with the 32GB model having a LED mini light, for example.www.swissarmy.comHave more to add? News tip? Tell us
