CARL Heavy Duty Paper Punch 3 Hole, 300 sheet

Los agujeros están corridos hacia abajo. Para perforar como se espera hay que poner el frente de las hojas en la parte inferior. El ajuste de distancia de la perforación a la orilla del papel no tiene seguro y se mueve relativamente fácil, esto da como resultado perforaciones a diferentes distancias de la orilla del papel.

This is in excellent machine

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.

We purchased one and immediately noticed the holes are not aligned. Reached out to the manufacturer who stated that would impossible and kind of called me crazy. I sent pictures and a video and then received no response. We sent that unit back in thinking maybe it was a fluke and the next unit that arrived was the same. I spent some more time looking at the unit and the issue they seem to be having is their alignment bar is not correctly calibrated. Luckily in my case the bar was too far away so I added a few pieces of chip board to compensate and was able to get the alignment correct. For a $300 unit this should not be an issue at all. The manufacturers response was also lacking to say the least.

When I first used this I had some trouble punching through much paper, but I found that with a few uses it went better. I also found that it really helped to have it on a lower table (mine’s on a table where the height is a little above my knees). This gave me ability to get more leverage and pressure on the lever. Maybe for a guy this wouldn’t be as important.A year and a half later, I still enjoy using the punch. It easily goes through 250 sheets of paper, although I think 300 sheets is a stretch. If the pages are stapled, it’s less because they don’t lay flat. I work in a school copy room and use it at least once a week. It has been worth the money and I would recommend this item.
