I used this saw on a project with Mangeris wood, which is HARD. The saw had more than enough power to do the job without slowing or binding, and cuts were straight and true.
The best part about this saw, though, was that it just feels right in your hand. Balance is critical in an 18volt tool, and the Milwakee is perfect. I spent all day with it and didn't get overtired. I've used other circular saws, both corded and cordless, but this is by far my favourite.
