Review: Positive reviews were correct! - Ordered this strictly off of the positive reviews that it had and it does not disappoint. Punches the sheets easily, and is easily adjusted as well.

### ⭐⭐⭐⭐ Punch works, automatic coil not the best
*by A***H on February 9, 2026*

Stamps coil cut well but have not yet been able to get the automatic coil to work correctly. It only works on smaller spiral coils. But gets stuck often.
