The Auto Wrench is not meant to replace specialty tools like pipe or torque wrenches, but the jaws open wide enough (up to 1-1/4-inch) so that it could conceivably replace a range of manual wrenches sitting in your toolkit. This is an ideal product for someone looking to buy a wrench that's both easy to use and versatile. At 8-inches, you could toss it in the silverware drawer and whip it out when you need it.

The area where this wrench really shines is in hard-to-reach spots where mobility is obscured, such as under sinks. A typical situation where the Auto Wrench would help might be one in which you're awkwardly reaching for a nut underneath the kitchen faucet. With a comparable manual wrench, it's conceivable you would fumble around with the adjusting mechanism for minutes on end, and then toss a fit. With the Auto Wrench, you'd simply press a button (positioned where you rest your thumb) and the jaws would open or close to your specifications.

We were a bit skeptical when we learned the Auto Wrench takes AA batteries and doesn't include a rechargeable battery. This means you'll need to keep some extra batteries around the house - or buy some rechargeable batteries -- if you use it frequently. However, the wrench isn't a power hog by any means. Black & Decker says you can get 650 cycles out of two AA batteries, which should be plenty for most people.
