Query: Not as good as I had hoped.

I sought a keyboard which would operate my entertainment computer from my position on the couch 10 or 12 feet away, mostly for Netflix, and occasionally for email or Amazon or whatever. It was tolerable but not great. Dropped characters frequently made spelling difficult. Left idle, the keyboard would go to sleep, by design, to save batteries. I never quite got used to that. It was necessary to tap the [Ctrl] key to wake it up, sometimes several times due to the dropped keystrokes. The dongle had to be in line of sight to the keyboard. The keyboard had to be angled just so. We did keep it for 3 years, so I guess we liked it ok, even though we grumbled about it often. Because we kept it anyway, I give it 4 stars. We replaced it with a Logitech K400, a much better device, which works well for us.
