  • Good value, easy to use, great results!
Number of Items: 1
I had several 'books' to bind, each about 100 pages, and with cardstock front and back covers. I bought this machine because it was cheap, and I didn't really anticipate using it again once I had made the books. I was able to successfully make a perfect book on my first attempt. The machine is relatively straightforward to use, and it's difficult to mess up as long as you take your time and are careful. The instructions aren't very good, so I watched a youtube tutorial. I kind of wish I hadn't though, because I figured out a better way of doing it. Instead of trying to hook each sheet onto the comb, I found it was much easier to stack the entire book as a block, then hold in in place while slowly pulling the lever to close the comb, capturing all of the pages at once. I would say the claimed 12 sheet punching capacity is quite optimistic. I was punching standard 2lb copy paper, and I found I could punch a maximum of about 8 sheets at a time without feeling like I was going to damage the machine. This is fine for small-scale production though. Once I got the hang of it, I found I could make a book in just a couple of minutes. I made a mistake with one of my books (printed the pages wrong) and I was able to use the machine to easily open the comb back up, remove the offending pages, and replace them with corrected versions. Once I had finished my books, I was looking around the house for other stuff I could comb-bind. I don't need the machine any more now I have my books made, but I'm glad I have it, and will definitely get some use out of it in future. ... show more

Its not top of the line but for the price you can't beat it. Easy to set up and use. Punches through12 pages at a time but struggles to do more. I built a 300 page manual in about 5 minutes.

  • Ready to use right out the box, easy to use and works
Number of Items: 1
For this homeschooling mom, it works!!! I spent $40+ (not including the 4 cab rides I had to take to them and back) at the UPS store last year in just binding. I had the good sense to print my stuff first. SMH, I vowed never to do that again especially since the girl miss punched and mess some up, which I noticed way into our school year. But back to my review. This is ready and easy to use right out the box and all I had to do is attach the handle. Thank you Amazon basics! Choosing the paper size was a no brainer since they have it labeled "letter size" and all I had to do was move the marker over to it. Again, thank you Ab! It punched my tester sheet nicely so I went to town and punched and comb bound our math curriculum. It was kind of a smooth punching process. It says 12 sheets at a time and I kind of tried to stick to that dictate. No guess work on the positioning of the pages to be punched. Just insert sheets until you can't go any further to insure edges don't get torn. Ummm, not to teach bad habits or anything but I punched my plastic cover sheet without thinking about it. I had it layered under my cardstocky back cover and it punched through. Not completely clean on the plastic but well enough that, holes were punched with maybe 2/3 spots that still had the top part that you had to pop off or snip. Tried it with just the plastic aannd will never do that again. My baby said "heck no lady! Ain't built for that". So, maybe not do that, lol....binding part was easy too and I used 2" comb binding. It's light but stays put on flat surface. Prayerfully it makes it through all the other work I have lined up. Pretty good value for my money. Now I feel like I accomplished something today, I'm going back to bed, it's Sunday and it just arrived so. I had to try it. ... show more

  • A great value with limitations
Number of Items: 1
During my working years, I had access to a heavy duty commercial comb binding machine and used it weekly. Now that I'm retired, I wanted something similar for personal use but didn't want to pay hundreds of dollars for a machine I would only need occasionally. So, I bought the Amazon Basics machine for less than $50, thinking that if it didn't work out I wouldn't be out much money. However, I found that it works very well! It weighs perhaps a third of my old office machine (or less!), so it's obviously not as durable, but (with care and a little patience) it does the job. Because it's light weight, I don't try to punch out it's rated volume of 12 sheets (maybe 4 or 5); I take extra time to make sure they're properly aligned before punching; and in the binding operation I collate 8 or 10 pages at a time onto the comb. But, as I said, it does the job, and the finished product looks identical to those I produced in the office. If you've never used a binding machine before, check out the process on YouTube or on Amazon's user videos, because the instructions printed on the machine are anything but clear. I've had this machine on my Wish List for months. I only wish I'd purchased it sooner. ... show more

  • It’s like a mule in an automobile society! Really!
Number of Items: 1
I have small lesson outlines (less than 20 pages) I wanted to make into little booklets. Instructions are none existent and I’ve used a binding machine before. The hole puncher really only handles 2-3 pages at a time and a couple times the end curled so that it wasn’t punched. There’s no way to see if the paper is in properly so sometimes the holes miss part of the paper so keep to 5 pages at most and it takes a lot of effort to punch those. Once I got thru that, the binding was a challenge. Works great for 2 page books (who needs that?); beyond that they do not release. Had to use a pair of scissors to get a 15 pager off. It is not heavy enough. Need one hand to hold it down while you open the spines. Guess it’s cheap. You get what you pay for. It’s awkward and difficult to use. ... show more

  • Works, but Cheap Quality
Number of Items: 1
It will do the job, but it feels very cheap when using it. If I do more than 4-5 pages I feel like I’m going to break the handle. It’s worked fine so far, but definitely only recommend this if your on a tighter budget.
