FLK TechBinding Machine with Starter Combs Set for A4-21 Hole / 450 Sheets Paper Punch Binder

Not going to lie In was returning this because it would not punch. BUT..... It was not broken. No instructions to say this but you have to make sure the comb binding prongs are closed before installing the handle, then install the handle in the upright position. Bingo, works like a dream. I have used binders for multiple years so I knew how it should function. I puzzled out why it wasn't going through and it clicked that I installed the handle not in the proper position.

Easy to use. Sturdy. Works great for the booklets for my class. An affordable

This machine is great and it is so easy to use. The price of the machine is affordable and it pays for itself in one use. I purchased it because I went to a store I will not name to get these books binded and they wanted a fortune. What they wanted cost more than the price of the binding machine. As you can see from the pics, I was able to do a pretty good job and I also have the machine for future use.

This is a good product for a small business or home use. In the past I have used industrial quality binding machines and this is not that. However, I do not need to use it often and it works fine for what I am doing these days. At this time I have only made about 20 booklets but it is still working well and making sharp punches and good holes. The plastic comb binding part works extremely well. I assembled eight 50 page booklets in about 10 minutes.Follow-up: I recently purchased clear plastic covers that were not prepunched. This unit cannot punch the plastic even one sheet at a time. (March 2024 update)

The punch works well, but there is a design flaw that makes the punched holes crooked when using the max margin depth setting for a Letter sized paper. The reason for this is that left side metal bracket that mounts the punching mechanism to the base (inside the outer cover) sticks out too far and prevents the left side of the paper inserting fully into the punch slot, while the right side of the paper does insert fully. This causes the punch line to be crooked relative to the edge of the paper. This only happens on the wide (5mm) margin setting, the 4mm and 3mm settings work fine.You can try to get around the issue by adjusting the movable red paper stop further inwards than the Letter size setting in order to miss the bracket, but this results in the first hole having a poor positioning relative to the bottom of the page and messes up the binder position.The only real fix for using the 5mm margin setting is to modify the bracket by taking the unit apart and filing back the bracket about 1mm so that the paper can insert fully. I did this for my unit and it works well now. I've posted pictures for where to do the filing. You have to remove some screws to take off the cover and release the bracket from the base, file the bracket down, and then put everything back together again.

When looking for Types of Binding Machine I had no expectations other than it needs to punch my paper projects. So far this machine has been great works as designed. I have used light weight paper as thin double sided glossy to as card stock with ZERO issues. I am looking to get the wire binding machines in the future. Overall great product and it’s fun!

I did not understand the difference between 8 1/2 X 11 and A4 paper. I have had to cut paper because the holes did not fit my 8 1/2 X 11 paper. The details say can bind up to 450 pages, but they only include small size binding combs so if you have a big project you will need to buy the size you need. You can always cut the binding strips to meet your needs so that isn't a problem. Easy to use. I couldn't find the binding combs on amazon for this company. I hope what I ordered fits the wholes it punches. I won't receive them for another 8 days.

This item came as expected with good time. I wish that it would have had different sizes of combs included with it instead of just one size. I am looking for more sizes but not clear on which ones to get. Otherwise, I am happy with it.
