i just got this today at target (first mistake, i always get my electronics and everything thru amazon, but i was in a rush to finish a project. unfortunately, i don't think i'll be able to finish it because this saw simply will die mid-sawing--even when it's plugged in. at first i thought the battery was dying, but even when i plug it in, it starts off strong, then dies. i'm totally returning this...i was stoked on getting my own saw, especially one that is cordless and hand-held, but this is a disappointing--too bad, 'cause i know black and decker makes really good hardware.
