Have had it for over 10 years and it never fails me The little plastic door over the cord is held on with duct tape, but other than that, it's a rock star. Also have a little one by Slime that I got at Walmart, first one I ever bought when I moved to Iowa and realized that tires deflate regularly when the temp drops to -10f overnight. It's stuck in the storage cabinet in the garage, haven't used it in 5 years since I moved back from the arctic...but last time I checked it still works.
