As a quality engineer these binders are good even though still requires some improvement mainly at seam areas. Nonetheless it seems they are too pricy!
I love these notebooks for organizing and also for presentations. They are easy to use just slide in your spine and cover and they look very professional. I also like the colors that these are available in - I always opted for white or black but color can do amazing things when looking at them on a shelf. I use the notebooks at home for organizing my knitting patterns and at work these notebooks are essential for projects and keeping our presentations looking professional and sharp.
Solid and flexible binder. Liked the ability to create a cover page to identify the contents of the binder. Also the side tab could be very helpful if you have many binders on a shelf. Also like the more solid feel of the solid vinyl binder as opposed to most binders that are just plastic coated cardboard. I believe the durability should be much better and it also has some flexibility for getting into and out of tight places that could tear other binders apart. While it is more solid and durable feeling then most it does appear to be lighter than similar binders which is a big plus if you frequently have to travel with it.
I enjoy this binder for the three ring release button it opens easily and quietly the binder itself is flexible the label on the spine is fun and makes it uniform if you have more than one binder side by side. The quality is superior to the other binders I have bought. The colors are fun.
These binders are attractive sturdy and allow full page identification in the front. They also have a place for identification on the edge very convenient. I use these binders in various sizes (1" 1 1/2" etc.) for Guide Books that I download for courses from The Teaching Company.
