I got a this to replace my Logitech G213, as I wanted a wireless keyboard that was a bit quieter. This one is indeed a bit quieter but feels great to type on - the key depresses the perfect amount, and you can really get in a good 'flow'.The buttons on the media centre are useful for YouTube and music, as is the volume wheel. The top buttons aren't too helpful to me since I only use one profile of lights (rotating), but if you like swapping then you can program them as you want via Logitech's software.The battery is long lasting. I want to say >30 hours - I find myself charging it maybe every 10 days. The indicator light on the keyboard will let you know when it's time to charge, and the lights of the keyboard will go red.The build quality feels good, and I've popped off the key-caps for cleaning and have put them back on without any issue. (Though I do have a little tool to use.) Some keys are, at this point, slightly worn down by my fingers but I do a lot of typing every day so I'm not really surprised that the most commonly used letters are slightly worn down.My motherboard on my PC doesn't have bluetooth and I don't have an adapter, so I use the Logitech Lightspeed USB plug-in that comes with the keyboard. Works perfect - I haven't had a single issue, so the receiver must be good.I would totally recommend this keyboard.
