i have had a few Jigsaws , old B&D from the 70's and a borsch , I do like the Borsh.
However, I recently started investing in cordless Dewalt (circular saw, planner , drill etc ) and purchased the cordless Jigsaw - NOT the brushless version
its great , not having to worry about the cable and works very well with both 2AH and 3AH Batteries
Although I'm only a DIYer so the usage is not high
I recently made up a Window seat using 18mm MDF and it worked well and the batteries on the Circular saw, Jigsaw, Drill and Impact driver , easily lasted the couple of days, without recharge, to construct and install
Although the blower set to blow across the sw, did not seem to clear the dust easily
