Title: Not up to the task
Review: This unit comes with McNair batteries. Need I say more? Once I changed them to Everready, the unit bogged completely down on some admittedly thick caulk. With a new tube of smoother caulk in place, the unit managed to nudge caulk out of the tip but did so in a cyclic pattern as the little motor struggled in cycles. Smooth continous delivery was the one thing I thought I could expect from a motorized gun. Cyclic blobs I can create for myself with a hand powered caulk gun. If Black & Decker had made this corded maybe the motot could handle it but all-in-all I wouldn't recommend this to anyone.
Is the review positive or negative?
