Summary: Love this calculator. I get a lot of compliments on it and it doesn't look or feel cheap which is what I always worry about with colorful calculators. I have no issue with it working with the lighting in my office, and I don't keep it bright here at all. Couldn't believe I got it at this price either - what a great deal!
Summary: This stopped working after 1 month. Within the first week out of the box, the display became decreasingly bright and within a month it would no longer display anything, seems completely dead. It has had plenty of opportunity to absorb sunlight, and for the first couple days it worked well, but it was all downhill after that. Disappointing for $20.
Great Bluetooth Keypad and Calculator - Canon X Mark I Keypad BT

Summary: This calculator functions easily on its own, but can be connected to Mac or PC with Bluetooth. You can use the "send" button to send the answers into an Excel sheet, which is helpful when doing your taxes,, budgeting, etc. Highly recommnded!
Summary: I really needed something to enter numbers in a spreadsheet or even text editor. You can accomplish this but it is very cumbersome since you have to put it into send results. Unlike a normal usb keypad that just send the number. It worked with mac os x and is key feel is OK.
