I've been using Maglite flashlights for years since they're durable, water-resistant, and come in a variety of sizes. I carry a 3 D-cell maglite on car-camping trips, and have a few mini-mags for backpacking or to stick in my pocket.
A while back, I went to change the batteries in my 3 D-cell maglite, and discovered that the end cap was stuck. Really stuck. Even using some clamps and a pair of vice grips wouldn't get it off.
As I later learned, the most common cause for this is corrosion from old batteries that leaked. I contacted Maglite and they told me to send it in and they'd take a look. About a week later, a brand-new model showed up at my door.
Turns out that they've worked out agreements with a few different battery manufacturers and they will replace flashlights at no charge to the customer when this happens. That's going above and beyond what I expect of a company, and that's why Maglite falls into the category of "Stuff I Like".
