Dyson vacuum cleaners. I've had mine for about 20 years, had to replace a part here and there, but it's just as strong as the day I got it. Probably the single best purchase I've ever made. A close second would be my Sonicare toothbrush.
I'm glad you said this. This truck comparison I've seen going around is getting tiresome. If someone's only measure of a work vehicle is bed length, I suggest they widen their scope.
Why'd you yuck my yum? :)
