This is an amazing machine. I wanted to have one for a long time and now I wonder why I waited! Essentially this machine punches holes into papers so that you can thread a spiral binding through the holes. This comes with a little clipper so you can clip the spiral rings and crimp them. You will need to buy your own spiral binders. Some things to think about: What kind of binding do you want? Comb binding is big and plastic. This one is a spiral binder. I wanted this type of binding because it seems like it would last longer than the plastic comb binding and it is easier to use when you want to flip pages back and forth. The number of holes per inch you want in your papers. It is my understanding that a 4 to 1 ratio is traditional and that is what this machine does. The number of pages you can punch with the machine you buy. This one says about 15 sheets if you are using typical typing paper/printing paper. I would say that is fairly accurate. I didn't count the number of papers, I just simply grabbed a small pile and punched. When I got too many papers I found I had to stand up and apply some pressure to get the puncher to complete the job. Do you want a special threader? This one does not have it. This machine is also a little bit cheaper than ones that have a special threader. Once i watched a few videos I felt comfortable buying this machine and saving myself some money. Essentially you punch holes in your paper, clip them together with a binder clip or two, then you twist the spiral into the little holes. Once you get it through the first hole, it twists right on. I was able to put together 5 books with over 200 pages in less than an hour while watching tv. It was that easy. i have put together my own daily journal and I plan on doing my own cookbook wiht all my saved recipes that I have stashed here and there. I have put together several spiral books for others and there are many other ideas.

What an amazing machine! Quality item, easy to ease, seems durable (I've only used it for 85 booklets, each with over 40 pages, thus far). The bonus is the electric coil threader... it is very quiet, works nearly every time, though sometimes a coil will go through but miss a couple pages... easy to unwind and correct. The whole experience in using this machine is excellent. Much cheaper than paying for this service... the machine has already paid for itself!

For the past 25 or so years I have been using a comb-binding machine for creating my own music books, or for cutting music books apart and rebinding so they will actually stay open on the music stand (don't music publishers ever think their customers actually want to use the music books they buy?). Until now -- coil binding is so much better than comb-binding! When the teeth of a comb binding pull out (as they inevitably do) and get bent, they can be a real bother to put back and I often simply need to put a new comb on the book. Coil binding eliminates that problem and it is so much easier to pull a coil out of a book if something needs to be added or removed or changed. This TruBind TB-S20 machine is easy to use, takes up only a tiny bit larger space on the shelf or table, and best of all, it is affordable! The coils are a bit more expensive than combs, but with the large variety of sizes and colors, they can be used to great effect and they won't break or need replacing the way that combs do. The one thing that this machine lacks is any instruction on how to use the pliers to cut and crimp the ends of the coils once they are in place on the book. HOLD THE PLIERS SO THAT THE RED DOT IS ON TOP AND IS FACING TOWARD THE BOOK. INSERT THE COIL AND SQUEEZE THE PLIERS SHUT AND THE EXCESS COIL IS CUT OFF AND THE REMAINING END IS CRIMPED SO THAT AS THE COIL TURNS IT WON'T COME OUT OF THE BOOK. If you need to remove the coil simply use a small pair of needle-nose pliers to straighten the end of the coil and then twist it out of the book. There's no need to buy the more expensive coil-binding machines which have electric coil inserters. It is so easy to simply twist the coil through the book by hand and this machine can be used anywhere -- it doesn't need any electricity. It makes me wonder why I didn't buy one years ago!

I have bound a large quantity of smaller booklets (58 pages double sided so 29 sheets of paper) and a couple of larger booklets (200+ pages). The instructions weren't very clear but google helped to clarify (as usual). For smaller booklets, make sure the depth adjuster is all the way in (see photos) or you'll find it hard to turn the pages. Hole punching is easy up to the recommended limit (20 sheets of regular paper, less for card stock) easy enough to hole punch each booklet in several batches. Just remember to ensure the handle is all the way up to release the paper. I do wish the base was heavier or had a weight to attach. The machine moves around when you are pulling the handle up. It is important to remember to empty the tray which catches the confetti-like pieces when you punch the holes. I found that I had to do so every 400-450 sheets of paper (again, some of that was card stock covers). The coil inserter requires a little practice to get the right pressure and angle to get the coil to thread but once you've got that down it's fast and simple. In less than 3 minutes I could insert coils in 20 booklets. You have to manually start the coils, as stated in the instructions and it's faster to do that for all the booklets then use the coil inserter to finish threading them. The crimper also take a little practice to get the right angle but so easy once you've got it down. Be warned oil does seep out of the joint, I put a piece of tape over the circle to keep it from getting all over the booklets as I worked.

This machine will help us to bind documents reliably for the foreseeable future. We had a heat-seal binder that has given up recently, and finally, this one will not fail. Thank you!
