  • Difficult to use
Size: 2" (450 Sheet Capacity) Color: 10 Pack , Black
Combs of this size are difficult to use unless your spreading machine is a large one. But with care, you will be able to bind documents that have a large page count. Here’s a tip: measure the thickness of your document, then buy the next larger size comb. For example, if your document stack measures 1 1/2 inches thick, buy combs that are 2 inches thick or you’ll never get all the pages in. ... show more

  • A Flat Nightmare - Buyer Beware
Size: 2" (450 Sheet Capacity) Color: 50 Pack , Black
Missed the return window and now I’m stuck with a whole box of these awful coils. I had a project to put together random printouts for an exam I’m studying for and I wanted everything securely together and without the bulk of a binder. I have other coils up to 1”, but my paper packet was about a whole ream of paper and 1” wasn’t going to work. Since, I’d run into issues in the past assembling books that exceeded an inch, I figured it might not be a bad idea to finally invest in larger coils. It was really difficult finding reasonably priced coils, but after many comparisons and reviews, I settled on these. Where do I even begin? First, and this may or may not be be a limitation of my binding machine and not the fault of the product itself, but these are hard to get onto my fellowes binding machine and get to stay on the machine and open long enough to put the punched paper on. Hard to determine if the issue is the size of the coils, the flatness of the coils or a limitation of my machine. Thank goodness I was not doing a bunch of books, because the whole coil came off every time I put one section onto the rings. I’d have to reseat over and over. I even lost the whole batch of paper off the rings and had to thread the entire packet of paper all over again. I finally got it seated semi well and figured out threading a smaller quantity (about 15-20 sheets) of paper, very carefully thread onto the rings seemed to keep it from being pulled out of its position on the machine. Given that my packet of paper was about 350-400 pages, it was very time consuming to complete. Second, there are ridges on the rings on both ends and the middle ring. This is a double edged sword, as at the end you’ll be glad to have the ridges to “lock” the rings into place or because of the flat design of the coil, you risk all of your paper working their way off the rings in an instant. On the other hand it makes it really difficult to thread your paper in the first place because they want to “catch” onto those ridges every time as you’re assembling your book and it makes it that much easier to dislodge the seating of the coil on your machine as you wrangle the papers on. “Locking” the three individual rings onto the base was a minor pain, but doable for just one. And I slightly panicked when I realized I had to unlock them, because after fighting with the whole process, I forgot to put the back cover on. But, that was doable for just the one. Thank goodness I wasn’t assembling multiple books. If I have to add anything else later, I don’t think I will bother. I don’t want to risk my sheets sliding off and having to redo the whole book all over again. I think I’ll just create an addendum book, using a smaller coil. The final problem has to do with its flatness. I don’t know what’s worse - the idea that these were intentionally designed to be a flat nightmare or that these were a flat defect and sold anyways to an unsuspecting consumer. Don’t think they will magically become round once you insert your paper on them. That’s what I naively believed. They won’t! This is the absolute worst feature of these coils. I thought when I bought them that maybe they were flat because of size and packing and that they’d “fill out” and round out once paper was on them, but that doesn’t happen. They stay flat! Well, I don’t care the reason, all I know is they are a nightmare trying to assemble your book and it’s mainly because of the flatness. There is nowhere to shove your papers as you’re putting more and more sheets on. It looks like you’re running out of room even though you have plenty of space. But, the flatness keeps you from being able to utilize the entiriety of the rings and it makes the papers slide up off the rings as you’re trying to add more papers. A fully round coil ring gives freedom for the papers to slide back as you continue to put more paper on. You don’t have to fight with a fully round ring. A flattened ring feels like you’ve hit a wall of max capacity when you’ve really only used half the space. If I’d known the issues with this, I’d have just went with the bulk of a binder and saved myself a lot of hassle and lost money. ... show more
