I do everything at my desk, so my keyboard acquires food in all forms from crumbs to grease. My daughter wants it declared a toxic dump.. so I have used everything from tweezers to dental sticks to clean out between keys. This product is a bit pricey, but after turning off my computer and cleaning, my keyboard looks absolutely new. No dog or human hairs stuck between the keys, no food, nothing. One stick did the job (though by the end it was worn down so reusing probably not in the cards). But for the truly easy way to get all the way down between keys and clean, this product DOES THE JOB and is easy to use!
