### ⭐⭐⭐⭐⭐ Works well!

### ⭐⭐⭐⭐⭐ I like it
*by P***A on January 3, 2026*

I like it. It is very easy to use and perfect for my lil home office. The quality is ok for home usage. It is worth for money

### ⭐⭐⭐⭐⭐ Quality binding machine at a good price point!
*by R***R on April 17, 2025*

This is a lower price point unit, but it met my needs very well. It punched and bound my booklets very well and is solid and very sturdy metal construction. I liked the bar type handle because it allowed the use of two hands to activate the punch mechanism. The binding unit is at the top of the machine and works perfectly. I had no issues with operating it. There is a tray underneath to catch the paper chads. The unit was packed well, came with a small instruction sheet that was helpful. I am using this unit to bind patterns that I purchased on Etsy and it works perfectly. It has three paper size settings as shown in the photos. You can change the settings by turning a knob and sliding the paper edge guide to the line graphic on the bed. It comes with a large box of 3/8” binders in black. They are high quality and easy to cut to size with a regular scissors to fit letter size sheets or smaller. I am glad I did not spend more money on a more expensive unit as this perfectly met my needs.
