  • Great value!
Color: Red Switch
This is my first true mechanical keyboard, and I got the quieter one (red switch), the keyboard is relatively light and slim for a mechanical keyborad. If you get the really slim ones, don't get this. I got this mainly for the feeling when typing, and if I would have tried at a store, I probably would have chosen a notch up clickier (the brown switch). quelity materials, cap keys can be excanged Mac/Windows, light effects very cool, very comfortable keyboard. Also price is at the lowest range for this type of keyboard, but it doesn't affect quality. Great quality overall. My advice if you like a clickier feeling get the brown switch (the blue switch could be too much of a click). Get the red switch if you still want to get the mechanical feeling but a bit quieter. ... show more

  • Good condition, and looks great
Color: Red Switch
Everything is great except that the package did not include the appropriate keys for a Windows operating system to replace the keys in the keyboard that correspond to a mac computer. The windows logo key was missing and the alt key was the wrong size

  • Surprised how much I love it
Color: Brown Switch
I'm coming from an Apple wireless keyboard - with the very low profile keys - the smaller one with the tiny arrow keys and without the numeric keypad. I write code all day and have been struggling with the Apple keyboard's arrow keys which have half-sized up and down arrows. It's very hard to find a good, compact keyboard with full-sized arrow keys. I was also excited to get home, end, page up and page down keys back in my life. Albeit a new layout, but something I can hopefully get used to. After a day of typing, I'd say I'm 90% transitioned from the very low profile Apple keys to these higher keys. After a week, I think I'll be totally comfortable. I'm really impressed with the build quality of this keyboard. It has a nice weight and feels super solid overall. And typing again on a clickity clack keyboard is so much more fun and satisfying. One concern is that it's definitely more effort to type on - not sure if that will have any negative impact on my hands/wrists in the long term. I tested the brown vs the red and I found the red to feel mushy. The brown gives a good sort of lumpy/clicky feedback. I did not try the blue and I think I might enjoy blue's even more prominent clicky feedback but it just sounds way too loud in video demos. Red and brown are very similar sounding and both of decent volume. If you need to type quietly, none of these will be for you. Although I have not gone through an entire battery yet, I'm apparently under 70% after 1 day of use. Compared to my Apple keyboard, which gets about 2 months of battery life, it seems I'll have to charge this about once a week. Not a deal breaker for me and somewhat expected given the LED lights. The RBG LED lighting is fun but something I don't need. There are a TON of options on the color patterns and effects. I'm interested to see how much battery life is saved by turning the lighting off. ... show more

  • Nice keyboard
Color: Blue Switch
It's nice overall. Slim, feels well built, everything is good. The downside is the lack of choice of keycaps. Another thing is that with the blue gateron switches on this the physical audible click seems to not match the actual trigger point, or something else funny is going on. For example if I press a key down really slowly it clicks but the keystroke is not detected at the same time. This doesn't happen during normal typing and not a big of a deal but something I did notice. Comparing it to Nuphy Air75 with blue gaterons Nuphy doesn't seem to have this, at least not as pronounced. Keycaps are nice overall. Transparent letters are nice as well, with the backlight it looks pretty. One thing that took me some time to get used to is the gap between the keycaps. For some reason I am making more mistakes typing blindly with these. Takes conscious effort to learn the layout better. The same thing for some reason does not happen on Nuphy Air75 which has very similar physical size and keys have the same distance but the caps don't have gaps and have slightly different shape. Maybe it's the keycap shape overall that trips me. Not a big deal in general and you get used to it quickly but something noticeable at first. ... show more

  • Best Keyboard and Perfect Keyboard
Color: Brown Switch
If you are looking for a small and elegant keyboard... this is it, i have the brown gateron switches, and it is very good, i always had cherry mx reds keyboard , i loathe the sound of the blues, but this browns are my favorite, the rgb is not as bright as the others, as many have pointed out, but its more than sufficient..i think, but it would be a plus if it was brighter, also the fonts in the keycaps are small so less light pass thru. in my opinion the quality of materials and construction is very good. its so beautiful and i am very please with my purchase. i mostly use it for gaming and the height does not make my hand hurt, you dont need a handrest. the bluetooth in my experience has been very good, it takes less than a second to activate when you transition from wire to wireless on windows11 with bluetooth 5.0. no idea how good the battery last but i guess with rgb is not much so i mostly use it wire. the only thing it doesnt feel so good are the on and off/win-mac switches, seems a little flimsy but only time will tell. i guess they figure nobody is going to be using those much, and i agree. for the price i would give this keyboard more than five stars... seriously. and the cherry on top that no other keyboard i seen has, is the included plastic cover, i have no idea why not all premium keyboard comes with this, is so simple yet so useful... ... show more
