This is actually a better deal than recent bare M18 mid-torque gen2 impact if you want the boot. These boots are awesome - fit well and protect well. As with the rest of "hackable" deals, the battery is just an unwanted overpriced filler that you would order and return for refund individually. This overpriced item actually reduces the price of the wanted item by $89.20 down to $159.80+tax for the tool+boot.
So order both, receive both, return battery for refund.
