I received a comb binder machine from the Amazon.com Vine product review program. I have wanted one of these for years but was putting it off due to the cost. I wanted it so I could print e-books I purchase. Lately I am also buying knitting patterns and knitting books that are self-published. I plan to also comb bind some documents I create for our homeschooling such as log books to document my children's educational work completed.
I find staples sloppy. Pages get much more tattered and torn when they are not protected by thicker covers. I have been three hole punching papers and using 3 ring binders but often those are too large and bulky, and then the holes on the pages tear during normal use anyway.
The machine I own is the Fellowes Office Comb Binder Pulsar 300 and it is considered a middle of the line product. I wrote my review for Amazon.com's Vine program and published it on my other blog. The rules of my BlogHer account prohibit me from publishing that review on this blog so if you want to read my review click here to link to read it on my other blog.
