My MIL gave me one of those hand blenders some years ago. It’s never even been out of the box. I find that I can blend things just as quickly with my Foley Food Fork, which is much easier to wash.
My husband came into our marriage with a machine that is a mixer, food processor, bread dough kneader, and several other things. I have never used it because it has way too many parts and needs to be flopped and folded in various ways just to use it. Again, I can mix whatever needs to be mixed by using my Foley Food Fork, chop it with a sharp knife, or knead it with my hands, all in less time than it would take to get the machine out, flop it and fold it for the particular task, and then find the various parts. It is also easier to wash the Fork, the knife and my hands.
BTW, my Foley Food Fork was my grandmother’s and, unlike the modern ones, is made of sturdy stainless steel.
We also don’t use the dishwasher (I am not sure it works anyway) or the Disposal (I’m not sure it works, either). We do use the microwave frequently as well as the stove top and the oven, and we make smoothies in the regular blender.
And I make paninis using my cast iron skillets – heat two of them up, set the sandwich in one of them and put the other pan on top of the sandwich, and Voila! a panini (or a medianoche sandwich.
