Needed a basic calculator with certain functions for High school Algebra math class. Had went to local stores and lowest priced items were all 4x as much. After digging online and researching brannds, I came to Amazon and they had many options to choose from. So glad I found this one. It is made well, doesn't feel plastic and cheap. It works well and does the necessary functions without being overly complicated.  So glad I kept looking and researching till I came across this one and made the purchase. It came in the mail within a couple of days. Love it!!!
