The test
Our bar: does it delete a daily chore?
Every gadget we track passed one filter before scoring: it must automate something you do every day. Soap dispensers remove a touchpoint dozens of times daily. Electric can openers turn a two-hand wrestle into a button press. Grinder sets make seasoning one-handed while you stir with the other.
The method
Why we score crowd behavior here
Small gadgets don't publish meaningful performance specs — so our scoring leans on the crowd: review volume 35%, estimated sales 35%, owner rating 30%. Tens of thousands of owners keeping a gadget on the counter is the strongest signal this category offers. Full formula on the methodology page.
The data
