They're a nice cheap way to personalise your otherwise generic looking product.
True and nice point .... if we are lots of technicians with the same instruments in the same place , it will be nice my tools to be able to be personalized by my taste .. or at minimum with the color of the company that I represent on the field , or with my own specific logo ( as freelancer ).
Many technicians in the field , they use even to paint their metallic hand tools, as an measure against theft.
But there is no chance to have the Micky mouse face , on my tools !!
But the point is what Agilent has in mind ?
Do they like to offer an practical solution ? If yes there is 256 single colors to choose from !!
Did they make those specific ones , as an experiment ? if yes ... it does not work for massive sales !!
I bet that they did it just to attract our attention on the Agilent brand .... and they had succeed it !
