Once again at DC we discover that those gadgets useless to some are vaunted by others. For everybody who likes something somebody else hates it, and vice versa.
For example the garlic press. In my case it's the Zyliss and I really like it, but not for all jobs. It produces sort of mushy threads which work fine in some recipes, but sometimes I want a very fine mince, sometimes finely chopped, sometimes coarsely chopped. Garlic presses are good at what they do but they can't be all things to all people and all recipes.
My Zyliss cleans out easily. I hold it under warm running water and poke out most of the garlic inside with my finger, then flip it over (output side up) and rub the surface with my thumb to push through bits that are stuck in the holes, and let the water force the bits out. Repeat once and it's as clean as a whistle, ready to be dried and put away for another time. (A dishwasher is unlikely to clean those little bits out, or at least not all the time.)
I have a couple stick blenders too (one is a Cuisinart). Stick blenders are useful in some jobs but again they aren't useful in many other purposes. I particularly like a stick blender when I have a small amount that I want super-blended and don't want to bring out a bigger tool. They're easy to clean too, just pop the immersion part and run it under hot water for half a minute, maybe throw a bit of soap on it if you've been blending something oily or greasy. Or throw it in the dish washer I guess.
