I been using the HKC since last August
99% of the time on the on the rail and couldn't been happier with results
Quality speedy cuts on framing specially in thighs spaces is one of the strong sides
It produces quality on trim and siding
No cords decent dust collection
I used worm drives since 1977 for framing , the last 7 months the worm drive hardly
came out of the truck except cutting rafters
Cutting wall plates on new construction was a breeze , it was faster and easier then dragging a cord all day
For rafters I would like to have the corded one , I hope they will be available shortly
How it will hold up ? Time will tell
If somebody abuses tools this is not for you and there are quiet few who do
If somebody works the tool hard , it will be one of your favorites with the TSC right behind
