Review on Wireless Bluetooth Number Pad: Portable 22 Keys Numeric Keypad for Laptop, PC, Desktop, Surface Pro, Notebook – Ideal for Financial Accounting and 10-Key Input by Aaron Vang

I was hesitant to buy a Surface Pro because the keyboard doesn't have a 10-key keyboard. However, once you find this Bluetooth 10 dongle, this is no longer a problem. It's small enough to put in my bag when traveling and fits perfectly with my existing keyboard. The keys are very similar to my keyboard, so navigating between them is very easy. I also really like that it's Bluetooth and doesn't require a dongle to connect to my laptop.
