Really great I see again between the low noise compared to an old wired Bosh then the perfect cordless to complete my Dewalt equipment with the swappable batteries, two 5.0ah batteries are enough to cut sheet metal for a whole afternoon, three would be better for no no having to juggle both charging and cooling time!

Battery a little short in duration and switch difficult to stop (especially with gloves).
