I use these notebooks to take information on the road with me. You can count on them getting dropped stacked under heavy stuff rained on and generally abused. I can rely on the covers to bounce back to their original flat state and the binding to take all the abuse without the cracks normal notebooks get. The 'D' rings are nice & hold a lot of sheets without causing the punch holes to tare. Rings open with the onetouch button and close evenly each and every time. My original notebook (still in use) is more than 3 years old.
Very Durable -- used in kid's bookback. This partcular binder only used for about a week. The binders are expensive but had a 50% off coupon - so I purchased 4 for under $20. Previous purchased binders lasted the entire school year and the rings never collasped or failed.
I'm 79 years old and have been in schools colleges and universities most of my life; and this is by far the most attractive practical binder I have ever used. Now with arthritis in my hands I can – with this binder ONLY – open and close it with ease.
I love these binders. I use them for college and my 12-year-old twins use them at school. They are the only binders that last the entire year without coming apart or having the rings start to misalign. There are great color choices for girls and boys. My daughter loves the patterned choices that are available only at the beginning of the school year. Great product!
