I love mag flashlight , and especially this one .  it be strong , the four d battery dont run out quickly , have a on\/off switch -lrb- unlike smaller mag model -rrb- , and doesnt generate much heat .  when electricity blacks-out , the torch mode of this flash light -lrb- the lense can be take off -rrb- be very useful - I can continue study \/ read \/ write for some while , as the light be strong enough .  i buy it about a year ago , as a small insurance in case the y2k bug would have take the electricity down , and it prove itself useful since .
