Summary: I use this numeric keypad with my Macbook Pro. I did not have any troubles getting it to sync. I am a teacher, and this is a helpful tool when I have to enter numerical grades. It goes much faster for me using the keypad and all of the numbers are close together.
Summary: I got this to go with my hybrid tablet, which has no numpad to its name even with the Fn key. As a numpad, it works quite well, and it's indispensable for people who have to type a lot of numbers. (You have to turn off Mousekeys if you have it turned on, though--the pad malfunctions otherwise.
Summary: This is my second 10 key. This one is so much better and it works with a MacBook Pro! Retractable cord is long enough to plug into the left side of the computer and stretch over to the right side for use.
Summary: I purchased this because my laptop does not have a 10 key and I am currently pursuing my MBA. I hate using the number keys at the top of the keyboard so this was a great addition. It's pretty small and the keys are easy to manipulate which is great for me because I type 10-key very fast!
Summary: The item is very inexpensive compared to other USB connected 10 keys. I was not impressed with the layout of the devise. I wish there was a kickstand to raise the upper portion to enable a slant; the flatness made it awkward and difficult to use. Also, the retractable cord was difficult to maneuver.
