Review on Wireless Number Pad: Portable Mini USB 2.4GHz Financial Accounting Numeric Keypad for Excel Data Entry on Laptop, PC, Desktop, Surface Pro, Notebook by Andrea Young

DO NOT BUY. It's a time bomb, 15 minutes after connecting to my computer I got the blue screen of death and killed it which caused it to reboot and die until I unplugged this device and turned off my computer and gave it a give it a minute to reset and reboot. In addition, this element is crooked and not straight, it sways when you press the keys. My computer shows no lasting signs of damage, but I will no longer use this device.
