Review on Efficient and Sturdy: Business Source Heavy Duty Punch 65626 for Seamless Hole Punching by Terry Myers

Have been using this punch for a year now. Not a day goes by that I don't use it. My office has reduced paper usage and I usually only need to punch 2-5 sheets at a time, but I needed to do more. After a year of use, the stamp began to wear out. The bars in the handle that press down the spring plungers have distinct notches. This made the punch more difficult to use and a bit noisy. I don't practice punching many sheets at once. It's easy to quickly smash through a few smaller sets and then hammer the grip for a big set or two. I am disappointed that this product is called Heavy Duty. I've used other brands for much longer in the past and subjected them to a lot more abuse.
