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!
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.
Black and decker really blew this one. This is a crude sloppy piece of work. It does not really do anything well but tries to do 2 or 3 things badly or sloppily. There is a much better strictly mechanical wrench sold at home depot that has all of the supposed virtues of this wrench but is of quality workmanship for the same or less money.

I can’t get this thing to grip anything at all.
I simply don’t understand all the hype, because mine has been in the drawer since I got it, and it is even too awful to pass along to someone else. New batts don’t help either.
Confused…
