Summary: At first I thought this keyboard was the best keyboard ever. I loved the feel, I loved the function keys. Not even a month after use its starting to act up. Will randomly disconnect from my computer and/or restart itself over and over. And now one of the USB ports doesn't work.
Summary: The keyboard worked well in the beginning, and I loved it truly... But then the problems started. Slowly the problems crept up. 1st the LCD options started malfunction. Some would go missing, others would refuse to work.
Pros: It worked well in the beginning.
Cons: Malfunctions, Lack of helpful support from Logitech.
Summary: Just got this in and nothing but trouble. The keys up top (menu, and up, down, left, right) do not respond very well. I have to press very hard down on them to get them to work. Currently typing on the keyboard now which i had to unplug my mouse from because the mouse in the usb port was not being seen. The keyboard it self is not being recognized there for no back-lighting, no macros, and only basic key functions.
Summary: I wouldn't waste money on a re-hashed product that had ZERO support for the first model. This should tell you something... ... I have not had ONE update to the software, in the 2 years I've owned it. BECAUSE THEY DON'T SUPPORT THEIR OWN PRODUCTS !!!
Summary: This is the worst new purchase I have made in ages! The display started flashing in loop about 2mos after purchase. Google says it's typical crappy Chinese quality control and wires are exposed where cables go into keyboard...and Google doesn't lie! The wires are hanging out and touching each other, causing a short. I wrap them in electrical tape as best as possible but the area is so tight it's impossible to get it correct at this point.
Summary: So I got this on sale to go with my mouse. I've read about compatibility issues with logitech and razer so decided to go all logitech. I'm disappointed in this keyboard in that the keys don't seem to feel as good as my steelseries. I feel like this keyboard was made for a button smasher. The menu keys for the led screen is trash. I have to really press down to get it to work. Also got a dead pixel...
Summary: They shouldn't have even released it, especially not for the price. Screen is way to small and reminds me too much of 90s. They have some cool features for the screen like viewing your cpu temperature and all the cores, but overall, the functionality of it isn't worth the buy at all due to the very limited amounts of things you can do with it..
Cons: The first one I got for Christmas and the screen would lose power without warning, which made it impossible to game with. I sent it back and they replaced it. The second one was hardly used at all when the w and s keys quit working.
