As with all other appliances
I have probably 150 or more blenders, I use them all the time, Right now on the counter is a GE from the 60s and a mid 50s 2 speed Osterizer, The one Turquoisedude had in the picture is a Montgomery Ward, I think Dormeyer made it, I have one, I have a Braun that is really good ,I have the first Waring , you turn the jar to switch it on, the best way to make cole slaw is with the blender, I use it making meatloaf,to chop the onions , make the bread crumbs etc..
