Review on Perixx Peripad-202H Black Wired Numeric Keypad With X-Scissor Keys, 2 USB Hubs, And Tab Key For Enhanced Productivity by Will Micheals

I have a silver ultrabook that lacks a keypad and I do a lot of numerical online homework projects (chemistry, statistics). This keypad looks nice and is slim enough to look like it came with the ultrabook. It has the Perixx logo on the top left corner but it doesn't really bother me. The keys work well except for the number '5' which I have to press harder than the other keys to make sure it shows up. I'm not exactly sure what the usb port on the side is for but sometimes I plug the keypads usb into it (makes a loop) to keep the cord from swinging/being loose when I'm bringing it to school.
