Exactly what I needed for Stats and Calc. Great product, light, easy-to-use, and has many functions. Delivered fast, highly recommend

I’m a math teacher and I love this calculator to check my students work. One of my students showed it to me and I just had to buy one. We like to call it the “god calculator.” It leaves fractional answers as fractions and rationals with the square root! It’s so cool and I love it so much!

PIECE OF JUNK AND WASTE OF MONEY... every time I hit the first key, it never registers, and always have to pay attention to make sure it shows up on the screen. I don't want to worry about if it registered the number I pressed. They made it look exactly like a Casio into fooling people to buy it but it's not even close to the quality. DO NOT BUY!! WISH I COULD RETURN AND GET MY MONEY BACK.
