I have have my 6d maglite for about 10 year now and still shine as bright and work as well as when I buy it . I go through a set of battery about every 2 year on average . dollar for dollar , this be the best flashlight . for $ 20 , it be very bright , battery last long enough , and it be also a intimidating clubber if worst come to worst . it be no wonder why law enforcement use Maglites . I would recommend this flashlight to anyone and everyone . affordable , durable , bright , and a self defense weapon if need to be .
