Summary: the plastic part for the holes cracked already, less than a week. I'm not rough with it or anything. Decent quality for the calculator buttons. i have a zipper pouch with a window that I put in my work folder, I just keep it in there. Shipped fast at least. I was looking for something like this and the style is perfect, very thin. But maybe if the binder holes part of it was cloth with reinforced holes. Maybe someday.
Summary: This is a great little calculator. I use it when I go grocery shopping to help keep on my budget. It fits right in with my 4" x 6" binder, that contains my shopping list and notes. I bought a second one to use as a back-up in case this one gets lost, stolen or broken.
Summary: These calculators are a great addition to my daughters high school supplies requirements. She needs two calculators one for her science folder and one for her math and these are perfect and will be secure and out of the way when she doesn't need them.
