Again, this is something you could do in approx 10 to 15 seconds with a pair of pliers, any time, any channel. Why anyone is pre-ordering a pre-dog eared channel is truly beyond me?
Iv killed a couple of channels attempting to dog ear them.
Also you have to get the angle just right when bending them or the dog ear is either ineffective or leaves a line when fanning.
If there's a channel that is pre dog eared to the exact right angle, that does exactly what it is meant to and saves us faffing about and possibly ruining our work tools, then for me it's worth ordering.
