have own several Mini Maglites because I always take it on trip and sometimes forget it be in the nightstand . they be build to last forever and I have always like the include spare bulb . this one advertise a `` New Multi-Mode Electronic switch '' for four function . I do not figure out that the ` switch ' be the normal collar because there be no instruction for this . go to maglite.com and watch the 38 second video to learn how to access the four funtion . maglite be still worth a premium price .
