Both my mother and my husband’s first wife were suckers for kitchen gadgets. My mother used them a few times and then relegated them to unreachable storage, mostly because they were more work cleaning, produced an inferior product, or had a defect - eg the vertical grill - the metal grill could drop below the stop and melted the plastic tray below. She has, various yoghurt makers, air & deep fryers, popcorn maker, one pot bench-top cookers and others. Her motivations (my opinion) was as an early adaptor of innovative ideas, (sometimes taken in by pseudo science), an impulse buyer and a lover of the shopping experience. My father was a thorough researcher & planner.
The first wife (who I did not know) had lots of kitchen gadgets, many unopened. I think a few things were at play here - a large disposable income, a love of shopping catalogues and later the internet, and with a number of “lifestyle” diseases and morbid obesity, I think she felt she was “doing something” by purchasing gadgets that promised weight loss, healthy living etc without changing habits. Quality was mostly disappointing - we opened one 7 years after purchase and it blew the fuses. I gave them away to anyone in the family who wanted them, and saw most of them passed from one to the other only to end up being given back to us. Fancy Juicers, mixers, slicers, pulping machines, fat eliminating cooking (it runs off, steamed off, mopped out, skimmed off), air fryers/cookers, one-pot bench-top (various systems), BBQs, rotisseries, coffee (all in one) grind, (one also roasted), perk, froth etc, pressure frother, cooker and MANY others.
I may be judging too harshly as my only single use gadgets are a hand-held beater and breadmaker - which I use to make bread, cakes & preserves. I use an esky & towels to make yoghurt, and I slice, squeeze juice and puree by hand with a knife & sieve. I use a microwave & stove top, electric kettle and toaster. My mother now gets packaged meals delivered and no longer cooks, the first wife died in her 50’s, my husband would prefer I used a machine, but I refuse if it can be done effectively and cheaply other ways, Besides, I hate spending more time scrubbing & assembling than using these gadgets.
