This is something almost unthinkable just a year ago: a 21 volt rechargeable 4 inch trimming chain saw for less than 50 bucks (I got it for even less on a coupon deal). Just a month or so ago, it was twice this price. This is the smallest of the electric chain saws I believe, I have seen 6 inch saws with more power, but for the price, this is a great deal. We will be spending time pruning our bushes with this device. How long it will last? Only time will tell. Still, for the price, it is very cool!!! Wonder if they make a holster for it???
