Over all we really like this idea just hope they can improve on it a bit more for the next one they make

I do like them quite a bit but make sure it fits your needs.

The rings are a bit slow to open in contrast to metal rings

I only have a few minor complaints: The lower ring tends to get bent out of shape a bit when using it on your lap (I would assume this is only a right-handed problem), large amount of paper can be a bit harder to do than in a traditional binder, but if you hold down the bottom part of the binder while turning it generally isn't too bad

Although guaranteed not to break, they are a hassle to pull apart, and because of the curves, a bit hard to load more paper into the binder

The rings are also a bit odd to separate which makes me worry the plastic will break sooner than later

a little bit dirty and broken

It was a bit more expensive than other types of binders, but my teen swears by them.
