Worst Kitchen Gadgets That Are a Complete Waste of Money

Open any kitchen drawer in any house and you’ll find at least three gadgets that seemed brilliant at the time of purchase and have been used exactly once. The kitchen gadget industry thrives on the promise of convenience, but most of these products create more problems than they solve.

After working in professional kitchens for 15 years and testing hundreds of products for this site, I’ve developed a very short tolerance for tools that don’t earn their counter space. Here are the worst offenders, why they fail, and what actually works instead.

The Hall of Shame

1. Avocado Slicers

These three-in-one plastic tools claim to split, pit, and slice avocados in seconds. In reality, the “splitting” blade can’t handle firm avocados, the pitting mechanism works about 60% of the time, and the slicing fan produces uneven slices that fall apart.

What works instead: A chef’s knife. Cut the avocado in half lengthwise, whack the pit with the blade heel, twist it out, and scoop with a spoon. Takes 15 seconds. You already own the tools.

2. Electric Can Openers

Unless you have limited hand mobility or arthritis (in which case, an electric opener is a genuine help), these countertop appliances are solving a problem that doesn’t exist. Manual can openers cost $10, fit in a drawer, never need charging, and work faster.

Electric can openers take up counter space, have motors that burn out after a year or two, and still require you to hold the can in position. The worst ones leave sharp edges identical to manual openers, defeating the supposed safety advantage.

3. Garlic Presses

Controversial, I know. Many home cooks love their garlic press. But here’s the issue: a garlic press wastes 15-20% of each clove (the skin and flesh left behind in the chamber), requires immediate cleaning to prevent dried garlic from cementing in the holes, and produces a texture that’s closer to paste than mince.

What works instead: Smash the clove with the flat of your knife blade, peel, and rough chop. For paste-like garlic, sprinkle the chopped garlic with a pinch of salt and use the flat of your blade to smear it across the cutting board. Faster, less waste, easier cleanup.

That said, if you cook with garlic daily and genuinely use your press every time, keep it. The worst gadgets are the ones that sit unused, and a well-loved garlic press doesn’t qualify.

4. Banana Slicers

This one barely needs explanation. It’s a curved plastic frame with slicing wires that cuts a banana into uniform rounds. A knife does this in about 8 seconds. The banana slicer does it in about 6 seconds. Congratulations, you saved 2 seconds and gained a unitasker that takes up drawer space and needs washing.

5. Egg Separators

Whether they’re shaped like fish, faces, or abstract art, egg separators are pure novelty. The two-handed shell method (crack the egg and pass the yolk between the shell halves) works perfectly. Your own clean hands work even better. Just let the whites drip through your fingers.

6. Electric Herb Choppers

Small electric choppers designed specifically for herbs produce wildly uneven results. They bruise herbs rather than cutting them, turning basil into brown mush instead of clean chiffonade. The motor is too powerful for the delicate job, and the blade spins too fast for any precision.

What works instead: A sharp knife and a cutting board. Stack the herb leaves, roll them tightly, and slice crosswise. A sharp chef’s knife produces clean cuts that preserve color, flavor, and texture. If your knife skills need work, our guide on choosing your first chef knife is a good starting point.

7. Countertop Quesadilla Makers

A flat cooking surface with a hinge that presses two tortillas together. That’s it. Your skillet already does this better because you can control the heat, check the cheese melt, and adjust the browning in real time. A quesadilla maker gives you exactly one heat setting and one level of doneness. Plus, it’s yet another bulky appliance that needs storage.

8. Hot Dog Toasters

Yes, these exist. Vertical toasters with slots designed for hot dogs and buns. They cost $25-40, take up counter space, and cook hot dogs to a rubbery, steamed texture that no one prefers over a grilled or pan-seared dog. A simple skillet on medium-high gives you the Maillard browning that makes hot dogs actually taste good.

9. Electric Knife Sharpeners (Cheap Ones)

This one needs a caveat. Quality electric sharpeners from brands like Chef’sChoice work well and have a place. But the $15-30 “pull-through” electric sharpeners with crossed carbide blades are knife destroyers. They remove far too much metal, create uneven bevels, and leave your edge in worse shape than when you started.

If you want an electric sharpener, spend at least $80-100 on a reputable model with diamond abrasive wheels and adjustable angle guides. For most home cooks, a good whetstone or manual sharpener is cheaper and produces a better edge.

10. Single-Serve Blenders for “Meal Prep”

The tiny personal blenders marketed as “meal prep systems” or “nutrition extractors” have 300-400 watt motors that struggle with frozen fruit and can’t handle leafy greens without leaving fibrous chunks. They overheat, the seals fail within months, and the proprietary cups aren’t dishwasher safe despite claiming otherwise.

What works instead: A decent full-size blender. Even a $40 blender with 700+ watts outperforms a $80 single-serve unit. If you want portability, blend in a regular blender and pour into a travel cup. For serious smoothie making, see our best blenders for smoothies roundup.

Gadgets That Are Actually Worth It

Not everything is a waste. Here are the kitchen tools that earn their keep:

A quality instant-read thermometer. Takes the guesswork out of meat cookery. No more cutting into a steak to check doneness. Our kitchen thermometer guide covers the best options.

A bench scraper. A $6 rectangular piece of metal that transfers chopped ingredients, portions dough, scrapes your cutting board clean, and crushes garlic. The most underrated tool in any kitchen.

A Microplane grater. Zests citrus, grates hard cheeses, shaves nutmeg, and minces ginger in seconds. It does multiple jobs and does all of them better than any alternative. Check our Microplane guide for recommendations.

A cast iron skillet. Sears, roasts, bakes, and fries. Lasts literally forever. See our best cast iron skillets roundup.

Red Flags When Shopping for Kitchen Gadgets

Before you click “Add to Cart,” watch for these warning signs:

It only does one thing. If a tool handles a single task that a knife, spoon, or pan already handles, it’s a unitasker. Alton Brown was right: the only acceptable unitasker in a kitchen is a fire extinguisher.

The infomercial makes it look easy. If the product’s marketing relies on actors struggling comically with normal kitchen tasks — fumbling eggs, mangling onions, spilling soup — the “problem” is manufactured. You don’t need a solution for something that isn’t actually difficult.

It requires proprietary parts or accessories. Gadgets that lock you into buying replacement pods, special cleaning solutions, or brand-specific attachments are designed to extract money long after the initial purchase. A good kitchen tool uses standard, interchangeable parts or no parts at all.

It has 4.5 stars but the reviews are suspiciously vague. Fake reviews are rampant in the kitchen gadget space. Look for reviews that mention specific recipes, long-term use, and real frustrations. If every review says “great product, works as described” with no detail, be skeptical.

It costs less than a fast food meal. Quality kitchen tools use real materials: stainless steel, hardwood, heat-rated silicone. A $4 gadget made entirely of injection-molded plastic will break, stain, warp, or dull within months. The cost of replacing cheap tools over time exceeds the cost of buying one good tool upfront.

The One-Question Test

Before buying any kitchen gadget, ask yourself: “Can I do this with a knife, a pan, or a tool I already own?” If the answer is yes, skip the gadget. Your kitchen drawers (and your wallet) will thank you.

The best kitchens aren’t the ones with the most gadgets. They’re the ones with a few quality tools used with skill and intention. A sharp knife, a heavy pan, a cutting board, and decent heat control will outperform a drawer full of unitaskers every single time.
