Popping a new battery in a smoke detector or adding salt to your water softener are easy fixes. But if you run into trouble or a necessary repair in a cramped, tight place, sometimes with no obvious fix or easy access, it can be a pretty frustrating exercise. Since flying blind is the absolute worst, […]
