I have purchased these notebooks several times over the last 10 years and I keep going back for more! They are workhorses in that the cover never splits on the seems the D rings make it easier to keep pages in place and move through different sections of the notebook. In addition the D Rings have a locking functions so you don't have to worry about your papers going all over the place if/when you drop it. And the last two points - The D rings always line up and won't catch your documents as you flip through the pages and last of all I love the clear view front back and spine. It makes it very easy to identify the notebooks for ease of finding on a shelf and you can also make them very attractive. Good bet for school office or home use!
I'v been purchasing 3 ring binders for a local community band for several years. Typically I'll pick up the Avery "Heavy Duty" binders. Although they say "Heavy Duty" they're not or at least for what i need them for. We'll put apprx 300 pages into a 2" folder. The handling and use they'll last about a year before they need to be replaced. The rings just don't stay together. I've recently purchased the above view binder which appears to be a little more rugged. At least the rings are a little thicker and they lock in place with the upper and lower locking tabs. We'll see how these last. We have some older folders that have heavy duty locking tabs. You can't open these with a crow bar. However neither Staples or your competitors carry these "Heavy Duty" binders in your stores.
We use this to hold all my special needs son's information from school and about school. We make chronological listings as well as by category (regular school info IEP info IEP reviews class room performance etc). The Binder is opened a minimum of three times a week and gets a fair bit of use being referenced. It works great because it is durable and strong. It can really take a lot of use and not show it. We also like the vinyl covering because it doesn't age at all and doesn't show wounds it receives when I accidentally drop it. Great product.
