I first encounter this flashlight during a `` ride along '' with a police officer friend of mine . for a few week , while I be consider become a reserve police officer , the local police department be nice enough to allow I to ride along with my friend Dave , who be a police officer for we local department . all they police car have the mag rx1019 's wire into the patrol car . now , I have have mag flash light -lrb- the battery power kind -rrb- over the year . however , when I first see my friend light up the night with the rx1019 , I could not believe how bright it be ! I ask he what sort of flash light it be and he show I it be a rechargeable mag . I be sort of shock ; after all , my mag light look the same -lrb- san the recharge stuff -rrb- , but be not even half as bright . Dave explain it be because the mag light in the car be always fully charge . wow , what a difference . after a few month of ride along , I decide against become a police officer . however , I do end up buy several of the mag rx1019 flash light . I even buy one for my Dad for Xmas . let I tell you , this be about the best flash light you can buy . it be always charge and ready to go - you never have to look for battery . it be super bright and really do a amazing job light up the night . in fact , it be practically like have a car headlight in you hand ! : - -rrb- that be how bright this thing be . the flash light really take a beating and be very well make . you can also buy aftermarket nimh battery if\/when need and these not only have no `` memory effect '' , but double the charge capacity . overall , short of spend hundred of dollar , this be the best flash light money can buy in my opinion . I use mine constantly . I live out in the forest and this flash light work great for light up the night and\/or when you want to shine it up into a distant tree to find a owl , etc. . if you be look for a top quality flash light , this be the one to get . I would give it 10 star if I could . . that be how fantastic a light it be .
