I LOVE this calculator. It is the complete opposite of the calculators that I used in middle school. This calculator is SO thin and lightweight. Not to mention, I love the fact that it could use different colors now, adds a lil bit more organization. It is obviously a lil bit pricey, but these things last for YEARS (provided you took well care of it). I remember a story where this person bought this for middle school, and even in college, she still uses the same thing! I like the fact that you could just charge this via a USB cable, unlike the old ones where you have to swap the batteries, its SOO convenient. I bought a protective case for it for protection and organization, I suggest people should also do that, if theyre gonna invest on an expensive calculator such as this.
