I am typing this on my brand-spanking new Ducky Channel Shine 5 RGB keyboard with MX brown switches. (sorry, didn't buy it from Mighty Ape because someone else had it on special $50 cheaper). Compared to my Logitech G510s this slab is miniscule. It takes up maybe 1/3 of the desktop real estate that the Logi did. I need to start a search and rescue mission to find it when I need to type. This is not necessarily a bad thing, not at all. Getting used to typing on this keyboard does take a few minutes, or in the long run it may take more than a few hours to get really good at it, but seriously: the typing just flows, even though the keys apparent height is somewhat different and I was snagging unwanted keys a bit at the very start, this is hardly an issue after an hour's use. Key action is very nice indeed.
Two things: after I turned on the backlighting on this keyboard the first thing I had to do is to lift the spacebar off and put a sticker on the central LED under the spacebar, because it was shining straight into my eyes. Impossible to use that way for me – that must be the way airline pilots feel when some idiot on the ground tries to flash them with a laser pointer. The other thing is: I will really need a wrist rest to use it. I'm used to the generous wrist rest on the Logi, and never had a problem gaming or writing for hours, with this, after about 1/2 an hour, my wrists are complaining and my fingers are developing soreness in the joints due to the changed angles that don't seem ergonomically all that good, even lowering my keyboard surface has not alleviated that problem. My wife walked into the room took a look, went ‘oooh, colours!’ and ‘it's LOUD’. Yes, it's louder than the Logitech dome-switch slab. I am bottoming out the keys at this point, I may no longer do so after getting used to it some. The supposed mechanical feedback on the Cherry MX brown switches on actuation just doesn't do it for me, I can simply not feel it. I might have been better off with a Red, with the lighter actuation force. Still.
Quality of the keyboard, at first flush, is superb though. Considerably better as a typing experience than my other foray into mechanical keyboards, the Gigabyte Osmium (or Obsidian or whatever it was called) that I sent back when one key started to some times miss, some times double actuate inside of a week.
