I am a high school math teacher. When my previous hole punch 'disappeared' from my classroom it took me a while to decide to replace it. My students have a lot of papers and I had many requests for one. I finally went to Staples and spent a considerable time reviewing the options. I think I made the best decision with function and cost combined. This low impact hole punch is great for large amounts of papers it hasn't jammed yet and the students love it as well. The larger size helps me keep an eye on it as well.
The Staples 3 hole punch works perfectly. Most hole punches are flimsy. This punch has a little weight which helps making the holes easy. Highly recommend this punch.
