Anybody use Maglite flashlights?

I have some I’ve had for years.
When they came out I was buying them as gifts. I gave one to a buddy that installed alarms. His cow-orkers had a contest to see who has the brightest flashlight and when he joined they all laughed at him because I had gotten him a small one that used two AA batteries while they had ones with D size batteries. After demonstrating his was not only brighter but could also be focused they all went out and bought at least one.
