I had used this machine at our school and found it to be a blessing when I had to prepare papers for my students, their portfolios and my person records as well as organizing my resources in binders. I purchased this machine and was thrilled with the delivery time. I plugged the machine in and have already punched 1100 pages. I LOVE IT!! The price was very reasonable and, when having to chose between a cheaper, smaller unit and this one, it was priced low enough for me, a teacher, to be able to buy the bigger and better of the two units. I recommend this product to every teacher.
