Is a Book Binding Machine Useful for Home or Only for Professionals?

Last Friday I was helping my cousin organize his notes and he mentioned getting a book binding machine. I had never used one before so it made me curious. I started thinking if such a machine is useful at home or mainly for professional work.

Looking at piles of loose papers made me realize how useful proper binding could be. At the same time I wondered if it is something people actually use regularly or just occasionally.

Later I checked online for more options. While scrolling many online marketplaces including alibaba I saw book binding machines in different sizes and price ranges. Some looked simple for home use while others seemed more professional.

Now I am thinking if a book binding machine is worth having at home or mainly useful in offices. Has anyone used one regularly and found it helpful?
