I did not object to its use - I said using one routinely is not something I would call an advanced technique, nor is it something wise to recommend to a general audience without some education. Certainly not everyone can afford combo wrenches, but if using an adjustable wrench it needs to be of very good quality, and needs to be used properly, especially with smaller sizes. I would guess that quite a few people even on this forum don't understand how to properly orient one when loosening vs. tightening, for example.
