We need to change the batteries 2-3 times a week or lose keystrokes.

The keys are easy to press with quiet keystrokes that are highly responsive

Receiver was inside the mouse at the time, and now translates my keystrokes as gibberish

It has started to miss keystrokes to the point of becoming aggravating

I noticed that a little green LED hidden in the slit between space bars would light up every time it missed a keystroke (see the pic).

Sometimes it will miss the first keystroke on the switch, but if you're watchful for that, it's no big deal.

Generally this keyboard is a great design and I love the separate number pad, (I believe this is the only Num Pad with a Calc button out there) , however the connectivity is awful on both devices, every time you pause for over 15 to 30 seconds they go to sleep and ALWAYS miss the first keystroke when you start typing again, I do not recommend that you buy this keyboard as this is extremely frustrating

so I have to keep the usb receiver on table, and so keyboard start missing the keystrokes

I spent half a day frustrated with the keyboard this morning, having it miss several keystrokes, restarted, etc., only to find that all it wanted was new batteries

It hasn't missed a keystroke or stalled once since this step.

Every single one of my keyboards has developed extensive lag and missed keystrokes

Then a 2nd, 3rd, 6th keystroke goes missing.

I find it comfortable, but after 5-6 weeks it started to miss keystrokes and eventually became completely unresponsive

It then takes forever to backspace and attempt to correct, with, again, one in three keystrokes successfully making it on screen

Dec 2017 the keyboard starting missing the first keystrokes.

For gaming, this keyboard doesn't handle chords or very fast keystrokes well - sometimes doesn't 'see' some

I also think the wireless connection can’t handle very fast typing without missing keystrokes, although this isn’t as often a problem compared to the spacebar

T e overall function of the keyboard is great.
