Jack buys damn near anything he sees in an infomercial because his stunted brain thinks 'if on tv must be good ook ook'. As a cook my primary tools are a good skillet, a good dutch oven, a whisk, some tongs and the most important tool of all...wooden spoon. You can have all kinds of utensils but you must have a favorite wooden spoon. It's just a fact.The funny thing about a Jack and his pointless kitchen gizmos is that a good chef could accomplish so much more with a crappy knife and a rusty old pan than Jack could ever dream of achieving with $10,000’s worth of gadgets.
You never see actual chefs buying this crap. People who actually know what they are doing spend their money on kitchen essentials, but they always go for quality. A good knife can be expensive but a skilled cooked can do magic with it. Instead of investing in his culinary education, going to cooking classes or shit like that, Jack thinks he can make up for his complete lack of skills by buying a $400 app-controled onion chopper.
Also while Jack will buy damn near anything he things will simplify cooking (A shit endeavor when you're a shit cook) not every single gadget is totally useless.
There's a group of chefs that test shit that shows up in magazines and tv and it's really a mixed bag. Check 'em out.
