Honest Opinion
I will be using this binder everyday for my classes and I solely selected this binder because of its color and aesthetic. It doesn’t have those typical plastic slots that easily come apart with time or bubble as you write on top of them. However I am disappointed of two details, which I should have listened to from previous reviews. However, I thought I could let them slide.The first one is due to the fact that I cannot just close the binder without the papers inside folding against the rings. As someone who is constantly in and out of my binder. This will get tiring having to adjust the papers each time.The second detail is the thin seams on the corner of the binder. I have not had the binder for much time, but I do feel as though those corners will easily come apart with time and tear my binder into three pieces.Overall, these two details kills the value that I paid for on this binder at $28.00.

Absolutely love it
I have had this binder for six months. I love it. It does not have an inside pocket--so buy some and add your own. It is hard plastic-- that's what makes it so durable. I am planning to get a 4" in the mint green, maybe even another color. Don't believe the negative reviews.

It will work for my needs
It worked ok, I guess. The construction is good and it holds a good amount of pages. The only thing that was not what I wanted was the length of the binder. It was about 1 1/2 inches long than the binders I already had.
