TIANSE Spiral Coil Binding Machine, Manual Book Maker Punch Binder with Electric Coil Inserter, Disengaging pins, Adjustable Side Margin, Comes with 100pcs 5/16'' Plastic Coil Binding Spines & Plier

I bought this as a classroom gift for my son's teacher. She was thrilled to have it and told me the other teachers have been borrowing it as well! They immediately had a class project to make their own books, which the kids loved. It works well. It was pricey but it seems like it will last a long time.

I love this thing and a hardly ever use it. I've had it for a few years now and have never had an issue with it. I have also never completed a single project that I have set out to make with this binder.Operating it is very simple and straight forward. If you've ever used a regular paper punch, it's like that. But way cooler.It's heavy duty, easy to use, and great for craft projects.

This product is amazing! I work at a retreat center and I have to bind books frequently for our guests. This machine is sturdy and easy-to-use and it has saved us tons of money by binding books ourselves. Our machine arrived with a motor that wasn't working as expected and we reported this to the Tianse customer support team and they shipped us a new machine in the matter of a few days. They were incredibly responsive. We love this product and we highly recommend it to anyone looking for a binding machine!

I write music, and this is exactly what I needed to coil-bind my own scores. No more bringing stacks of pages to the copy center and waiting weeks to pick up the finished project -- only to discover that they put in some of the pages upside down. Now I can do it all at homeThis punches nice, clean holes, and the long side of a standard 8.5"x11" sheet can be punched in one go. I use a lot of "legal size" paper -- 8.5"x14" -- and those require two passes. But everything lines up perfectly, so that I was able to do dozens of stacks of these long sheets with no mis-punched or off-center holes.A couple of modifications would make this a five-star product:* When I saw the electric cord, I assumed that you would just push a button to punch the holes, but that's not the case. There is a manual pull-over lever that works the punch. The electricity just spins a little grooved cylinder on the top of the unit, that assists in loading the plastic coils through the holes punched in the sheets, which is cool, but not really necessary. Motorizing the punch itself would be a definite plus.* Making the unit a bit wider so that it could punch 14" sheets in one pass would be useful. On the other hand, that would make the unit larger, and more difficult to fit in tight spaces, so maybe it's fine the way it is.* Some clear instructions on how to use the odd set of pliers (included) to dress the ends of the coils, would be handy. I had to go to Youtube to figure this out.Finally, be aware that LONG coils don't seem to come in sets of assorted sizes. Each set is 100 (or more) of one size only. Since a set can run you $30 or more, if you need several sizes, this could be expensive. OTOH, 11" coils DO come in assorted sets, so if you're never binding anything longer than standard letter-sized sheets, it can be fairly economical.Over all, a good, well-built tool, which does what it's supposed to do, and does it well.

I use this machine to bind materials that I use in my special education classroom. Adapted books, social stories, individual packs of materials for my students to trace or write on, the possibilities are endless! I have even gotten brave enough to try the electric feature to run the coils through....and it works!!! It took me a minute to get the hang of the cutter/crimper pliers, but the instructions are spot on. I haven't really moved the sliding thing that adjusts where the edge of your book goes for hole punching, but it is super easy to adjust. You empty this binder just like you do a hole punch. This one has a drawer like feature that slides out so you can dump the contents easily into your trash can. I have learned that carrying the binder from home to school without emptying that drawer will leave your floor covered with tiny little glittery discs....they look pretty and vacuum up super easily, but be warned...they can annoy your husband! I definitely recommend this product.

I love it when I receive the perfect product to get the job done. I print my coloring books on 67lb bristol vellum and it punches without issue. Of course, I can't punch 20 pages as my paper is thicker and it shouldn't according to its specification. It easily punches multiple sheets of cardstock as well as 140lb watercolor paper. Oh, and punching 8mil covers is not a problem either (I punch 3 at a time with ease) Binding isn't much of a problem either as long as everything is lined up. I read the reviews and took a gamble and it paid off. This is a great little machine!

The machine is great but I do have a few qualms. One is that I had to do several tests to get the letter size holes just right so there wouldn’t be one on the end with half a punched hole. Another thing is that depending on paper weight you can only punch through so many at a time. Which is not that big of a deal to me. I also struggle a bit with cutting the coil down to the right length but that’s really probably a me thing. Overall I still think it’s worth the money.

The machine is generally well built with sturdy constructions. HOWEVER, the paper guide DOES NOT lock down properly. Without that functionality, it becomes increasingly difficult to punch paper consistently.Unfortunately, there is no way to get at the assembly. The part on the inside which the knob is attached to is not accessible.It comes with a guarantee and you're supposed to return it to the manufacturer with proof of purchase. Conveniently, they left off any kind of shipping address or instructions. Or even general contact info.Avoid.
