Mine is fairly new (within a year)
Intermittently stops working..
Good batteries,
One day I accidently knocked it of the saw horses and it worked when I picked it up..
Next time it did it,I smacked it with my hand.. slightly tapped it with a hammer handle..
Nothing..
So I dropped it..😂
Picked it up and works fine😮
(I'm not suggesting anybody drop a $250 saw on the floor deliberately)
