Hi all, Im sorry if this sounds like a bit of a Newby Question, but I want to purchase a Good quality Flashlight, and am looking at the Jetbeams.... BUT... Could u maybe explain the difference IN LAYMANS TERMS.. between the
Jetbeam M2S and the Jetbeam RRT1
Does one do something the other doesnt?
Thanks for your replies!!
