I have an Olight obsession and started with my husband buying his original M 20 Warrior at a local gun show.....I then bought my E3 for my purse and then it was on!!! My favorite has been discontinued and is the Diffuse....I have the Santa Clause version and have gifted MANY.....next is the Obulb and Sphere...the red, white and blue Warrior, got my husband the Zombie clip pro and my new favorite is the mini rechargeable magnet keychain light.
