The SKYLOONG GK104 Pro supports N-key rollover USB and 2.4 GHz which tested successfully using Aqua's test. It defaults to 6KRO with Bluetooth as expected. Switch Hitter confirmed no chatter with these keys either, and seen above are all the functions with dedicated keys on the base layer. The keyboard ships with 96 switches by default, but can be configured to have anywhere from 95 to 104 keys as previously discussed. As such, you can get the missing keys back if you so desire. Also, the R. Win key is replaced by a Fn key, so it's not reflected above. The Fn key is not as critical here as on smaller form factor keyboards, given the larger number of dedicated keys already on offer. Instead, SKYLOONG is using the Fn layer to enhance your quality of life. There are a lot of pre-programmed shortcuts on Windows and macOS, including for volume and media playback control, choosing the connectivity method and the client to connect to, RGB LED control etc.
I did a double take the first time I realized this keyboard had onboard speakers! There is a typing sound effect by default on some keys which can be toggled through some preset options, and a full-fledged voice when you turn on calculator mode as seen in the video above. This can be very useful for those with visual impairment, but it's only relevant for some things. For most others, I suspect this novelty will wear out soon and thankfully SKYLOONG makes it easy to turn off the sound altogether with Fn + numpad 0. The numpad screen also displays the current date and time, among other things, and this too can be easily set as described in the user manual.
The other screen is optional on the GK104 Pro, and yet I suspect most will end up going for it anyway. This 2" TFT LCD display is large enough, colorful enough, and crisp enough to be quite useful in more ways than one. Seen above are some hand-recorded videos, hence the shaking given the other hand was on the keyboard changing things, showing the screen in its default GIF mode, an actions-per-second/minute screen which can be neat to track how efficient you type, and there is also a home screen with more information available at a glance. The screen has its own controller and onboard menu too, complete with some typos, allowing you to set some things and choose the theme to better match your keyboard. I did have some fun uploading random photos and GIFs which looked so much better here than on pretty much any other keyboard with integrated displays we see on the market. Let's also not forget the knobs which can do, among other things, volume control, zoom in/out, switching between programs, media playback and much more—provided you can get it set up in the software anyway.
Seen above is the SKYLOONG GK104 Pro lit up in a few different lighting effects. Given the keycaps are backlit, although only on the front where the legends are and the rest of the keycaps are dark and opaque, I think it's fair to say anyone wanting an impressive light show is probably going to look elsewhere. The good news is that the LEDs do their job in making the keycap legends easily visible in a dimly lit environment. The placement of the legends will also work fine for most people given a typical viewing angle, although there will be a short learning curve for you to get used to this. The colors are also fairly accurate here, and I recorded two videos to also show you the screens in action. Oh, by the way, there is also a microphone in the keyboard—in addition to the speaker—allowing for lighting effects that respond to the sound being played around the keyboard. You can thus have the keyboard be a spectrum analyzer or dB meter of sorts too, it's crazy how much is packed in here. Also, in case someone is wondering, it's all done locally on the keyboard. In either wireless mode, the LEDs and the screens turn off after ~10 s of no activity by default, and you can change this using Fn + Ctrl on the keyboard itself in 10 second increments. I was fine with the default setting itself to save battery life, but you can also turn on/off the screen and LEDs as you desire. Battery life is amazing as a result, and a lot of credit has to be given to SKYLOONG for putting in two separate 4000 mAh batteries here. You will see both battery levels represented in the numpad screen too, during charging or in use. I had this keyboard on hand for over a month before I wrote this review, and honestly I still could not get it all the way down to zero unless I kept having all LEDs and the larger screen on all the time. In practice, expect to see over a month easy of regular use and charging is simple enough. The 2.4 GHz connection is ideal for low latency, especially with SKYLOONG seemingly having gone for a mediocre Bluetooth transducer with the occasional cuts and ghosting. Charging the battery takes ~7 hours owing to the absence of quick charging.
The KTT Rose Silver switches used on this sample are one of many such speed switches that seem redundant in this age of Hall effect switches that offer customizable actuation starting at even 0.1 mm of travel. Still, there will be a market for mechanical switch keyboards for a while and these are still among the "fastest" full-size mechanical switches as a result of the switch actuating at ~1.2 mm compared to the usual 2.0 mm. This is basically the KTT equivalent of the Cherry MX Speed (Silver) switch thus, including with the medium force actuation of ~45 gf. The difference here is that the stem is pre-lubed, there is added dust/spill resistance, and the switch does feel smoother. On the other hand, KTT isn't exactly known for its high quality switches and reliability, so the QC lottery will be riskier here. SKYLOONG says these switches are made exclusively for the brand, but we don't know if this entails a higher level of quality assurance or not.
As always, the sound of a keyboard is based on more than just the switch type. So when comparing sound clips, consider the keyboard as a whole. In this case, I have provided above an example sound clip of me typing on the SKYLOONG GK104 Pro keyboard sample at ~105 WPM as it comes out of the box with these KTT Rose Silver switches. For context, you can find sound clips from other keyboards here, including those with linear switches. I did bottom out constantly here because these switches are prone to doing so past actuation, although this now helps demonstrate how well damped this keyboard is. These are extremely smooth switches which helps of course, but they are complemented well by the foam and PET sheets used which remove any reverberations and pings in the typing experience. It's not as deep sounding as some keyboards with denser (metal/wood etc.) cases and plates, and yet I am generally pleased with the typing experience. Some of the stabilizers felt less uniform than others though, and this perhaps goes to the quality of materials used here.
