CherryKW X ULP Ultra Slim Wireless Mechanical Keyboard. Multi Device Function MX Ultra Low Profile Switches.

I rarely write 5-star reviews, because I understand how bell-curves work. To be 5 stars means that an item is exceptional. This Cherry Keyboard IS.My old Logitech Illuminated Keyboard K740 is getting really old. I tried to replace it about 5 years ago, but I couldn't find anything worthwhile to replace it with. Well, circumstances caused me to look again, and after some internet posts mentioning this Cherry KW X ULP, I decided to give it a go. I'm REALLY glad I did.This thing feels quality all-around. It's hefty for it's slim profile. It's got a clean, jet-black metal face, the classic white letters are wonderfully illuminated and pop with crispness. The keys feel wonderfully sleek and responsive to the touch. Keys snap into place, but do so smoothly, like a high-end old typewriter (but with much shorter key travel). It's classy looking, full-size, easy to type on for those of us made to take typing lessons on full-sized keyboards in youth, and just all-around great.I've paired it via bluetooth and USB to my laptop. Both works great. I paired via bluetooth to my android phone, and it worked wonderfully too! I haven't tried the dongle, and don't really plan to since 2.4ghz always gets interference from my other devices, but so far connectivity is excellent. Zero complaints whatsoever. There's nothing I DON'T love about this keyboard. It's all I was hoping for. It's actually WAY BETTER than my old Logitech k740!Two things to note that SOME might find unappealing (though I am perfectly content):1) The function keys are defaulted to the media-control/shortcut functionality. To use the actual FUNCTION keys requires holding the FN key. To swap this, the press the key combo FN+CTRL (not the same as a lot of other keyboards). I Hope that helps.2) It's a very loud, clicky keyboard. I love it. Very positive feedback when typing, both tactility and audibly - but I understand that isn't for everyone.

I really like chiclet-style keyboards and have never been able to find a nice mechanical one. This is a nice mechanical one. It's also wireless, which wasn't a big need for me but has been very, very nice.The keys are quite clicky and feel very consistent. The keyboard is sturdy and does not flex much for its thinness. The rubber feet keep it in place, and the flip-up feet offer a good base if you prefer that keyboard angle.The keyboard doesn't require any special software, though there is a macro software offered by Cherry. I haven't tried it.In particular I like the number of ways the keyboard can connect to things: wireless over the dongle, wireless over two different Bluetooth channels, and wired. I have the dongle plugged into my PC, and a Bluetooth connection to my work laptop. Pressing FN + F3 switches instantly to Bluetooth 2, and pressing FN + F1 switches instantly back to wireless. It's very convenient!The keyboard backlight is minimalist and clean, with a few colored keys which can display different colors. The Cherry icon on the top right corner goes from green to yellow to red to show battery status. The Wired/Wireless key is green, and the Bluetooth keys are blue. The FN, Caps, numlock, etc. keys are red. The status colors show even if the backlight is off.Battery life has been solid.The main downsides so far:* It's expensive.* The included user manual seems like it's generic to Cherry keyboards, so I had to go online for specific questions.* The Cherry key in the top right by default turns the Windows key on and off. I'm not really sure why this would be necessary, but with the software you should be able to remap the key to something else.* Locking the FN key on/off is a hidden keybinding with Ctrl + FN, which took a minute to find. It's also rather easy to accidentally press this since the keys are right next to each other.* The keys cannot, as far as I know, be serviced on their own.* The screws in the back use a small torx bit which could make disassembly less accessible.* Sometimes the wireless connectivity can be spotty. The only physical objects between the keyboard and the dongle are my desk surface and my PC's chassis, so I'm not sure if this is a problem with the keyboard or a problem with some sort of external signal interference. So if you're planning to play games where you need it to be reliable, maybe plug it in and use it in wired mode.

First of all, I have never seen or heard of this keyboard, prior to stumbling across it while browsing Amazon. I was not aware that Cherry made such a high performance, ultra low profile keyboard like this! There were not too many reviews, so curiosity got the best of me, and I went for it. What I got was one of the highest quality keyboards I have seen at this price point!The feel and looks of this keyboard sort of remind me of the Corsair K100 Air. That keyboard is made mostly for gaming, this one could work in an office environment, as it is very quiet. It is very lightweight, yet not much frame flex, feels very solid when typing, I'm using it right now to write this. I was also not aware that Cherry made any key switches of this caliber. They are, of course known for very high quality, full travel key switches, of many types. This is the first ultra low profile key switch from them.Yes, it is made in China. But the board is designed in Germany by Cherry, and very well constructed, mine has zero flaws, and is super solid and pleasant to type on...IF you like very low profile, low travel key switches. They have more travel than say, an Apple Magic keyboard, and the feel is much more tactile and pleasant. But they feel nothing like your typical Cherry MX key switch!Overall, I'm very happy with this purchase, even at its quite steep price point. The quality is there, and if you like very low travel key switches, you'll love typing on this keyboard. I do not use it to game on, so sorry, I can't give much input on that aspect. Almost forgot to mention the outstanding backlight, each and every key is very well, and uniformly lit, looks amazing in low light. It has amazing attention to detail, including a very nice looking shiny chrome bezel around the frame...this keyboard is expensive, but it looks and feels expensive! Zero regrets on this one!
