I purchase one of these each year for records kept in our office for reference. We color code and use red for our purpose. There were no reds in any size this year. That is the only complaint. Otherwise these binders are easy to grab strong as an ox always open easily have great label options and look good on our shelves.
Purchased for my high school student. We bought 2 at the start of school. I purchased 2 other notebooks elsewhere and she asked me to go back and get these to replace the ones purchased elsewhere. She loves them. They stack well for carrying around the school and they also don't rip the pages as easily. It is very pricey compared to what I purchased but hopefully they will last all through high school.
I'm using this binder as a reference book. I like the fact that I can add my own artwork if I want. I especially like the spine tab it allows me to label each binder so I can easily pick the one I need.
I had to buy it for a school project and decided to invest in a slightly higher-quality binder that I could use over and over again. I think I picked a winner! I suppose "poor color variety" is a con but honestly? I do not care at all.
