Pros: Comfy, quiet and proper for fast typing keyboard
Cons: Quality is out of any competition
And here is why...
First, I ordered this keyboard online, when it arrived, I saw quality issues straight away, the glued back panel had too big gaps (purchased from official Logitech retailer)- I could fit business card there... I ordered another one... and another one... Well, the third example of this keyboard was OK, relatively OK, I still wasn't impressed with the built quality after my Logitech Edge Dinovo keyboard, but since there wasn't anything alike (illuminated wireless) on the market, I still left it (worst mistake I could make)
Obviously, after few months, the glued back panel gap raised and was about the same as on the examples I sent back initially, but ok, left it as it is, not a first world problem, even though there were sharp edges around, I don't touch them every day but stil, a bit annoyed by the fact.
Cleaning issues- if you ever had anything under the keys, you have two options- either live with that the that key is stiff now or broke it down when trying to remove it. It's impossible to clean this keyboard, I'm very accurate user but somehow something happened to get under right shift key, it wasn't usable properly anymore, tried to remove it by instruction and it broke down, when tried to find a replacement key- no luck, couldn't find a retailer selling that particular key, so disappointed about that cos for the price, unmaintainable keyboard is unacceptable for me.
Anything good? Yes, obviously, typing experience is great, keys are soft and because of low profile, they're easy to use. Also, keys are very quiet, I liked that keyboard, wish it had Edge Dinovo built quality, purchased it mostly because of backlight but... after around a year, I can throw it out now
Little about backlight- it have two options- auto or manual, I used it on auto, found it quite good and didn't feel a need for a manual options. Also, auto turn on is a big deal, sensor is somewhere under keys, and it works absolutely perfect, just put your hands down on keyboard and it is lit up already! Or you can just wave over and it will turn on too. Never ever had need for brighter backlight or anything else, in that part, this keyboard is great.
Keys. As mentioned before, they are low profile, very soft touch feel and quiet too, great for typing and if in office, your colleagues won't be annoyed. Key location- there is dedicated sound level buttons and calculator button, but other are mixed with Fn buttons, so you can chose in software, which would you like to use as primary- Fn or F1-F12 buttons. I'd prefer some dedicated buttons for music player and maybe for keyboard brightness, other Fn keys are useless for me, like, why would you ever want to check battery level by dedicated key on the keyboard? Or, is there anyone who actually switches off PC from the keyboard?
Short conclusion- if it was maintainable keyboard, it could earn at lest 4*, but since it's like one time paper plate, it can't earn more than 2 stars! Very disappointed as Edge Dinovo was a great product and I really looked forward to replace it with this, but unfortunately, I wasn't satisfied with this item since day 1!
