It's probably OK for something about the thickness of metal siding or tin roof panels, but don't try it on body metal. Back when I ran a high school body shop we had a drill motor with a scissors-type shear clamped to the front that did a pretty good job on bodywork if the cut was straight or slightly curved, but it was much sturdier-looking than the one in that ad. Getting it manufactured, shipped from China or some other offshore factory, and selling it for less than $25.00 ought to give us a clue about its quality!
