TIANSE Binding Machine, 21-Holes, 450 Sheets, Comb Binding Machines with Starter Kit 100 PCS 3/8'' Comb Binding Spines, Comb Binder Machine Book Maker Perfect for Letter Size, A4, A5 or Smaller Sizes

If you aren't needing making a large numbers of binding daily then this is your best choice. It is cheapest on the market (at least when I got it) and it works! It is not easy to cut 15 sheets at once, but probably around 7 at a time. The punchers aren't very sharp I think, so you will be faster and better off doing around 7-8 sheets at s time. On thinner copy paper, you can go up to 12 sheet. The thicker paper is definitely around 7sheets only. The front/back covers that protect back/front I punch as two sheets at a time.It is easy to attach the handle and seriously either for organizing your school prints (textbooks, class notes, documents, etc) or business stuff, this is totally enough. If you need industry strength that needs to be used for hundreds of sheets a day, this may be not strong enough. Otherwise, it is a great addition to your home office or small business office.

This book binding machine is perfect for what need. Easy to use and works well. I am using it to make booklets of 40-50 pages and it is great. It is sturdy and made of quality material. Very easy to move around and store. Highly recommended!

I like this machine. It is easy to use. I do recommend getting stiff card stock backing sheets and clear covers to give books some stability. I didn’t look when I was buying, but I would now look to see if there was a machine that came with a variety of spine sizes. I had to order some larger size spines. I now have way more spines tan I’ll ever use. I do recommend this machine. It is easy to use and outputs a nice product.

After getting a quote from Office Depot and Office Max for printing and binding a few house guide booklets for our short-term rental, I realized I could practically buy the equipment for the same cost, and here we are.This 21-hole comb binding machine does exactly what it promises. It punches clean holes through standard letter paper and can handle up to 450 sheets with the right comb. I’ve been using the included 3/8" combs (100-pack starter kit included) to create multi-section house guides that look clean and professional.It’s manual, so don’t expect high-speed production—but for small-batch jobs like welcome binders, menus, or guidebooks, this is perfect. I’ve used it for letter-size and A5 sheets so far with no issue, and I like that it's not just limited to one paper size.The build quality is solid for a home office machine. Setup was easy, and the handle operation feels smooth and controlled. Just make sure to align the paper well before punching for best results.Pros:Affordable alternative to print shop servicesClean, consistent hole punchingComes with 100 combs to get you startedWorks with letter, A4, A5, and smaller paper sizesGreat for home officeCons:Manual operation takes a bit of time for large batchesComb binding isn’t as sleek as coil or thermal (but way more convenient)Summary:If you're running a short-term rental, homeschooling, or just want to create professional-looking booklets without recurring costs, this binding machine pays for itself quickly. I’m now making detailed, multi-chapter house guides at home that look just as good as what I was quoted for at the print shop.Rating: ★★★★★ (5 stars)A smart tool for DIY pros, small businesses, and STR hosts alike.

Bought the binder for a real estate office and it works perfect for creating market analysis. Very good value for the money and has been a great addition to the office supplies. We are over put it on the bottom shelf and if it’s perfectly.

Purchased this binding machine to help keep my notes and other things together so I don't lose them. It was a little confusing to me at first on the comb ends on how to place them on the machine. Once I figured it out it was pretty easy. Just make sure you decide how many holes you want before punching. I had to trim off a couple of the ends before realizing I had to many holes for what I wanted. Will use this for our church directory.

I wanted this product to work. I bought all the supplies to make user manuals for a new program. Printed them and started punching.First, the punching takes a bit of time, 12 sheets max. The punch collector on the bottom us useless. After one manual, I had punch tabs all over my desk that resembled a well-known election ballet in Florida. It was a mess! The handle is weak and the machine actually "flexes" when you pull down to punch. Very weak design and flimsy operation.Second, I tried punching 12mil clear sheets. They punched with a little bit of effort but getting them out was nearly impossible. The punches stayed attached to the clear sheet and you physically have to "rip" the cover out from the machine.Trying to get them into the tabs is a feat in and of itself. It takes effort and patience as the machine "holder" that holds the binding open moves around a lot. With the flex of the binding in the machine itself (can't hold the binding open steady at all), it's very difficult to align the holes up for the tabs in the binding.Unfortunately, this machine is more of a headache than it's worth, and the sad part is, I needed it for a project and it took way longer than it should have. It's too used to be returned so it'll have to do but won't get used often, unfortunately. With so many supplies, I think I'll be searching for a sturdier machine. You get what you pay for, I guess.

I personally live this machine as I enjoy creating and putting things together and this machine helps me to do just that. From assembling story book to school projects. You name it I am able to put it together using this machine. I got this machine as a really cheap rate and the delivery time was so fast. I was so excited to get it and I have no regrets. You should get one too. You can create your own little projects especially for children.
