ZOMM's Wireless Leash plus is a hockey puck you clip onto your keychain and forget about -- until things start to go wrong. Tethering to your iPhone over Bluetooth, it'll start raising hell if your phone gets too far away from you. It's also a speakerphone (with a noise-canceling microphone) for taking calls on the road, a personal attack alarm, and it'll call the emergency services at the push of a button. Paired to the free myZOMM app, you can geotag your car so you remember where it is in the multi-story lot or check out the last known location of your most precious stuff. It's shipping now for $80 and a further $30 will get you a safe driving kit, not that we need to remind you that driving with a phone in your hand is a bad thing, right?
