Review on Enhanced Black Kensington Pro Fit Ergonomic Wireless Keyboard (Model K75401US) for Optimal Comfort and Functionality by Victor Hurvitz

Good keyboard, but all very cramped. While I'm trying to hit the backspace key, I keep hitting the lock and locate the trash button. There is no separation of F1 - 12 keys, so I keep hitting the wrong keys. The arrow keys are also too close to the right CTRL and 0 keys on the keyboard. If you have graceful trump hands this is a good keyboard but I have big hands. Even with small keys, the ergonomic design is quite comfortable. However, that is not the reason why I gave it 4 stars. I'm sure it just takes some getting used to. The Note 4 is because I sometimes get a double entry when I press a letter just once. I'm typing pretty fast so I know it's not a lag. It doesn't happen often. So for the price it's not that bad.
