CarMD
Do you ever fantasize about being your own mechanic so you can stop torturing yourself about whether you’re getting ripped off at the shop? This handy tool brings you one step closer to becoming Mr. Fix-It. Just plug the handheld tester into your car’s OBD2 Data Link Connector (found under or near your car’s dashboard), turn on the ignition, and then wait while it collects your vehicle’s information. Its color-coded LEDs provide a quick clue as to whether all systems are “go” or if there’s a problem. Then connect the tester to your computer to download reports via the CarMD Web site, which gives users access to accurate, value-added data, including potential problems and their solutions, estimated repair costs and more. It works on all cars, light trucks, minivans and SUVs manufactured for use in the United States since 1996. $89.99. (www.carmd.com)

A cool biometrics fingerprint sensor — a major “wow” factor — means no need to remember passwords and it even features two built-in cameras — one for on-the-go video conferencing and another for taking photos. $1,800.
