Another cordless wonder
I bought this a few weeks back with anticipation of once again not having to drag a cord around. Works as well as corded version with one exception. When cutting in a tight circle in heaver gauges, the latching mechanism tends to disengage. This forces one to use both hands to keep latch in position. Marking it down on this one glitch.
