I just find them so difficult to use. Even my good quality one is crap, there's too much play in the jaws, which means that you have to adjust it every half turn of the nut. Fine if you can get to it, but when you're replacing taps on a bath (to pick an example close to my heart at the moment) and working with both hands under the bath, out of sight, while lying on your back on the bathroom floor ... I wish I'd just gone out and bought a 34 mm spanner, regardless of how much it cost. But I suppose sometimes they can have their uses.
