Bests & Worsts Reviews from Amazon

Like others, I bought this to replace a Logitech K400, which suffers from the worst keyboard layout in the history of computing. The keyboard layout on this is much better, but a slew of other issues make the keyboard unusable for me. - The function keys are set to media keys by default and you have to press the Fn key to make them act like the F1-F12 keys. Type Ctrl-F4 to close a browser tab? Nope, you just put your computer to sleep. Try to re-train 10 years of muscle memory to use Ctrl-Fn-F4 instead. - The documentation is extremely sparse. There may be an Fn-lock function that would resolve my first issue, but it's not documented anywhere and I haven't been able to find it by experimenting. - Complete lack of Home and End keys. - Poorly thought out touch pad. Very jittery and extremely difficult to accurately position the pointer. It is sooo frustrating to move the pointer over a button and have it jump away when you lift your finger in order to tap on it. - There is no Caps Lock indicator (beep, LED or on screen display) and the key cannot be disaBLED. I'm glad I kept the box so I can return this. I'll suffer with the K400 until someone finally gets it right.
