this be my third LED Maglite . my family and friend keep sneak off with they because they be so useful and bright . I keep my LED Maglite in my messenger bag at all time . I like to be prepare , and this flashlight be very compact . the flashlight casing be 100 % aluminum . it definitely feel solid , and can survive a nasty drop or two ... or six ... or twenty . the lens be slightly recess and be plastic , but it have not crack on I yet . the lead itself be not replaceable like other non-led maglite bulb - but LEDs last thousand of hour longer than traditional bulb . I would not worry about need to replace it . if there be a problem , Maglite provide a limited lifetime warranty . the beam be surprisingly powerful . I have be able to see thing more than 150 foot away with ease with this little flashlight . I have not have a need\/opportunity to test it at longer distance , but it can allegedly cast light up to about 300 foot . there be also four mode - high-power beam , low-power beam , strobe , and SOS . I have not really need the last two mode , but I find myself switch between high and low-power on a regular basis , depend on what I be do . Bottom Line : - extremely durable . - extremely bright , especially consider it be small size . - four different mode . - limited Lifetime Warranty .
