Review: Easy to use - Works great, I had to bind 200 pages, and even though I only did 8-10 sheets at a time it was really fast and easy. I would recommend it.
Review: Great little maching - This is working like a dream. I used to have one at work and when I retired I went without for a while. Great little machine for putting these small books together. The last one I put together was a crochet pattern that I printed off and then found it had about 20 or more pages. It is working so great as I put together a crocheted nativity!

### ⭐⭐⭐⭐⭐ Easy to use
*by B***L on January 17, 2026*

### ⭐⭐⭐⭐⭐ Great little maching
*by J***O on December 20, 2025*

This is working like a dream. I used to have one at work and when I retired I went without for a while. Great little machine for putting these small books together. The last one I put together was a crochet pattern that I printed off and then found it had about 20 or more pages. It is working so great as I put together a crocheted nativity!

### ⭐⭐⭐⭐⭐ Homeschool help
*by N***A on September 26, 2025*

This is incredibly helpful for printing workbooks at home! It's basically a fancy hole puncher that allows you to add a spine to a stack of paper. It takes one screw to add the handle and it's set up. Really easy, no tools required. Helpful hints: Make sure the paper is setting flush every time, sometimes the paper scraps get stuck in the bottom, especially if you've overloaded it, and it can cause misalignment and a bad punch job. Word of warning about bigger bindings: we use electrical tape to keep the big bindings together otherwise the weight of the paper will bend the spine times and completely remove itself if you were to pull it by the spine off the bookshelf. (Don't know if that was clear, this tip has nothing to do with this product except making it super successful for you.)
