What's the difference between the Standard and Metric? Sorry if this is a stupid question. I'm a girl just start to learn about tools.

metric is measured in mm and standard is measured in inches.

I am completely baffled by the amount of green this post has received. IMO this is one of the worst tools ever created. I am grateful for the friend who gave me one as a gift, but maybe I can help someone from making a purchasing mistake. In the few cases where the large ends are able to fit within the working space, usage has been limited by the long handle length or lack of ratcheting. I suppose one could use it to loosen drain plugs and change oil, but a simple adjustable or open end wrench is much lighter and easier.

So that was the only difference, the measurement?! I was thinking of the physical of the instrument itself, thought that they might be shaped or stuctured differently. lol

Thanks for the clarification!
While there aren't any structural differences between SAE(Society of Automotive Engineers-standard) and metric, there are some structural differences to be aware of when buying tools. If you look carefully at the "sockets" in the "dog bone" wrench you will see they are "short" and 6-sided. Sockets also come in "deep" and 12-point (12-sided). A 6-sided socket provides more contact area and reduces the likelihood of "rounding the edges" of a nut or bolt-head when tightening or loosening. 12-point sockets come in handy if you have a tight working area with short rotational distances. Similarly, a deep socket may be too long to fit into the space available (and over a nut or bolt-head) and a short socket may be too-short to reach a nut threaded onto a long bolt. (I should mention that there are some other differences, but this should be enough to get you started.)

I have resisted the temptation many times to buy this and posts above have helped me do that again. I have so many wrenches and sockets-- why would I ever want a product that reduces my need for them?!

Oil and transmission drain bolts is what I bought it for. Serves this purpose well. With 3 vehicles I don't always remember the head sizes, so I just drag this under the car with me.

Usually where this comes into play is with your vehicle. If you're working on an American make, then bolts and nuts are usually SAE or Standard. If you're working on an Import make, then the bolts and nuts are going to be metric.

It makes sense. Don't work on cars so i guess i don't need this one. I think some open mouth/adjustable wrench will suit better for around the house.

Please correct me if I'm wrong, Delzy, but what I think your trying to say is that a professional mechanic needs dependable tools that are more aligned with specific tasks. Pro brands like Mac and Snap-On are made with better alloys to optimize strength and weight. They are also built to closer tolerances so they can transfer loads more evenly and are less likely to deform under load, break, corrode, or otherwise change dimensions. Other time-saving advantages include available accessories, marking, indexing, and ease of cleaning. (I've been generalizing here, and some mechanics might take exception regarding impact-sockets.)
