Heavy Duty 3 Hole Punch for 300 Sheets - CARL Black & Silver Paper Punch | Ideal for Office, School, and Home Organization

I purchased this and returned it because it was significantly less expensive for the identical unit elsewhere, price matching wasn't offered and the knobs holding the platform that sets the distance from the edge of the paper to the holes were striped upon arrival.But the replacement unit works and it is fabulous! HIGHLY Recommended. Here's why:1. It really makes a difference being able to set the depth distance from the edge of the paper to the holes so as to avoid putting holes in text!2. It uses a solid bar to hold paper in place so there will never be misaligned holes!It also adjusts for paper length, but I haven't needed this feature yet. But I'm glad it's there and it is simple to use this feature.I want to thank previous reviewers for mentioning that when the number of pages gets higher, the machine needs to be placed on a lower table so that one can use their body weight to punch the holes. Otherwise the bar takes an awkward amount of upper body strength to push down, especially for me, a 5" tall female. If you're taller you won't have an issue.This comes with experience, but you'll know the machine has punched all the way through the paper when it has one final push beyond what you would think finished the job. And, it won't release the paper until the handle is brought completely to the top position. No short cuts or grabbing papers out of the machine. Bring the handle all the way to the top.Finally, it is not huge which is nice. It fits pretty much anywhere when not in use.Just as an aside, I did speak to the manufacturer prior to returning the unit and was told that they would "do me the favor" of sending replacement knobs, as if receiving a unit with stripped knobs was acceptable to the manufacturer and as if it wasn't under warranty of fitness to do the job it was advertised for and intended for during the first 24 hours of receipt. Horrible customer service but an otherwise excellent product.
