Nice anecdote (if only all drivers and cyclists could be so friendly to each other).

I ride on city streets and very rarely have the light on high (either headlight or taillight), for the purpose of saving battery charge. And I point headlight downward, never toward drivers' eyes. Since you have used both flashlight and the Magicshine clone, how does one compare to the other? Do you think the MagicShine clone's beam is pretty decent? I may try to get a C8 flashlight mentioned above to compare (thanks to everyone).

P.S. a question about battery chargers:
For charging one single 18650 battery, will there be harm/danger to use a charger that can charge more than 1 batteries simultaneously? e.g. using a dual charger to charge just one battery, would the other, empty slot be a accident hazard? (IOW should I get a singer charger for the C8 flashlight, or it doesn't matter if using a, say chargers for 4 batteries to charge 1 battery?). Thanks in advance.
