Excellent quality, easy to use and provided me with the service I actually bought it for, arrived before expected time.

This is a very good, strong machine. I am only giving it 4 stars because of a few small things. One is that it ignores typical US paper sizes. The letter size can be punched using 1, 6 and 12. The #12 position is mislabeled, see the yellow arrow. I will point out that the size of the holes is smaller than those in typical notebook paper. Whether this is good or bad is totally a matter of opinion. On the plus side, this is set up for many paper sizes and is quite configurable. It easily cuts through lots of sheets of paper, and through cardboard.

This book binder is solid as a rock made out of metal and wood. The hole punchers punch right through many sheets of paper at once and the arm is made to crank down with force which is good. Everything checks out for me on conception and execution of design. All of the hole punchers are easily adjustable and the whole thing is self explanatory in operation. If you are the foreman of a job site or an executive member and you want to make a lot of book/pamphlets to hand out to the engineers on a site or the construction crew or even if you run a type of laboratory and need to make a lot of safety spreadsheets or procedure books then this is your tool. This is what you've been looking for. It will take a lot of pages and pop enough holes through them that you can run those little plastic spiral book binders through them and have an actual book or pamphlet that will last a long time and it will keep many pages from getting lost or disordered. This could be especially handy if a type of safety book is supposed to be on site somewhere and the inspector is on his way. You could theoretically just print out the books you're supposed to have and bind them write there saving yourself and your company demerit points.

This is a wonderful hole punch and it's exactly what I've been looking for. Most hole punchers are very cheaply made and they really don't lend themselves to such adjustability regarding both the paper sizes and with the margins! This is a must for anyone that enjoys multiple sizes of ringed binders/ planners and loves making things to put in your ringed binders.I love the visuals that are printed on the machine so you don't have to worry about your measurements.I was a tad confused at first because the box is labeled "Binding Machine," not "Hole Puncher." It's a hole punch, don't worry!It's sturdy and very well made. I feel very confident that this will last much longer than any small ones on the market that I've found. I fully recommend this.
