Black & Decker AAW100 8-Inch Auto Wrench Adjusting Wrench

First tried to use this wrench to remove copper piping from a laundry sink. Wrench simply would not grip the nuts, it does not close tight enough; at least for that application. Only thing it was good for was taking to the tool chest to size the craftsman wrench I needed.

I does work fairly well on most nuts, but still can not compete with a quality wrench set. I am going to put it in the emergency kit in my truck. I guess if space really is an issue, it is a good buy.

I bought this wrench because it looks so innovative. When I had it in my hands, I realized that my assumption was wrong. The reasons are:

1. The switch is at an awkward location. My thumb is not there when I grab the wrench.

2. The power of the motor is too weak. So there is no feeling that the jaw is tightened.

3. The shape of the handle is far from ergonomic. It usally slips out from hand.

4. Overall size is too bulky. So it is not agile enough.

One day, there must be an occasion when this wrench can be helpful (I hope), so I just keep it.

This is the best new tool to come along in twenty years. What a great idea and excellent implementation of it. This is the coolest crescent wrench I have ever seen. It makes it so easy to work on projects where you have different size nuts to tighten and especially when working where space is limited. The electric adjustment on the wrench is amazingly quick. I mean you hit the switch and it's snug up against the nut ready for you to start turning. This wrench is not fragile either. It can apply as much torque as a regular crescent wrench. It is amazing that it is not that much bigger than a regular wrench. It will fit in all thoses tight nooks and crannies where sometimes you need to get a wrench into. Amazon doesn't have any in stock yet so I found mine at Lowes Hardware. The Thornton Colorado store sold their whole display in one day. I drove up to the Longmont Lowes to get one and it was well worth it. GREAT TOOL!

This is the second "Auto" tool that I got from B&D that just sucks. It just doesn't tighten enough to be of any use. I can understand the safety issues of why it won't close too tight in case it is used on something like a finger, but in order to tighten a nut and bolt, you need something to tighten on that, and this just doesn't.

This wrench has internal parts of poor quality. The mechanicsm is driven off a small rubber belt. Mine worked approximately 3 weeks. Then, when the button to move the jaw was used, the motor would run but no jaw movement. I removed the screws from the plastic casing to find the belt had broke in two pieces. It appeared to be dry-rotted. It is a cheep internal part that, when breaks, renders the entire tool no more valuable than the $5 crescent wrench from Walmart. Don't waste your money.
