Binditek Spiral Binding Machine for Letter Size/A4/A5, Electric Coil Inserter, Manual Round Hole Punch, Adjustable Side Margin, with 100pcs 5/16" Binding Coils & Plier & Binding Cover

Unfortunately, the edge adjuster is not working properly. It is extremely hard to pull it out which makes it impossible to set at the 4.5mm margin. I have wasted a lot of paper trying to punch holes at the 4.5mm margin the result is always the same the holes range from narrow to wide. Basically, you only have two settings for the edge adjuster either completely pulled out or completely pushed in but not in between. I have not used to electric coil inserter therefore cannot say if it works properly. Nor have I used the included coils as they are too small (8mm) for my needs. It is obvious quality control was missed prior to packaging item. I will be returning the product.

Great Machine! Used to bind printed workbooks for the kids. Buy bigger binding coils if for school the ones it comes with are small, the covers work great.

Easy to figure out and use. I’m a self-publisher and educator and I pump out about 10 books per hour. You can make small notebooks or massive books, thin or thick. They’re not kidding when they say 20 pages. Don’t try 25 or you’ll only produce 1 book per day!

As a homeschooler, spiral bound workbooks are the GOAT. But they’re pretty expensive. Even the cheaper printing companies take weeks. I had to take matters into my own hands. With 5 kids, I was on a printing light budget. I decided I would help myself and my local homeschool friends. So far, the machine is very easy to use. It’s a hole press. But adjustable, heavy duty sort of one. It punches great. The depth adjustment is a little finicky but once you figure it out it’s fine. I haven’t tried the electric spiral inserted yet. Primarily because they only sent half the power cord. I haven’t contacted customer service yet, but I assume when I do, they will help me. However it is quite easily to insert the rings by hand. The hardest part is using the pliers. I plan to watch a Youtube video of how best to use them, as getting the end of the rings just right is possibly a skill. Overall though I am very happy, especially that it came with clear covers and rings (though this size is limited to use with pretty small booklets). I have been able to print so many more things without having loose papers everywhere or having to print the next page every day… it is glorious. Easy to pack our materials and go to the library. Yes I highly recommend. You can make a small business out of it if you need to ;)

Great tool
