Q: How clean do the cuts come out compared to using snips?
A: The tool is designed to produce uniform cuts with consistent shape, which can be harder to maintain when cutting manually with snips.

Q: Does it stay accurate when you're switching between different types of cuts?
A: Yes, once you're familiar with positioning, it maintains consistent results whether you're making tabs, notches, or miters.

Q: Is there much setup involved before you start cutting?
A: No setup is required beyond positioning the material in the jaws, so it’s ready to use right away during install.
