I don't hate them either. And for the $10 (2AA) -$25 (6D) price, its a decent light for the average flashlight user. Unfortunately, Maglite is content to stay with outdated technology.
In fact, I have more Maglites than any other brand. That will change soon, as I won't buy anymore Maglites until they start updating their outdated incadescent line with LEDs (knowing how Maglite is so inclined to be stuck in the stone age of lighting, that might be a while). Even if Maglite insists on sticking with incadescent bulbs, a simple introduction of a better reflector can somewhat improve the beam quality (reduce the holes and rings). They don't seem to want to do that though.
Once you get LEDs you'll never go back. A good LED flashlight has such great beam quality. The problem with Maglite, as I see it, is that the beams suck. The beams they emit are full of holes, blotches, and rings. The beam starts out yellow and gets brown quickly. The Maglite flashlight itself is well made, durable, reliable, and has a nice switch. But, the beam quality and low brightness for the size (many flashlights are as bright or brighter than Maglites and are yet much smaller) are huge detractorants, IMO.
Conclusion:
Maglites are well made, reliable, durable, and a good value for the price. Its also a nice looking design.
However, their beams absolutely suck and they are too dim for their size (brightness to size ratio). Their reflector and bulb technology is outdated.
