Works great!
The price is a bit high, but the product performs well! I discovered that having the RGB lights on the whole time made it so that the battery drained really fast, but when I contacted support they got me the newest software update to be able to turn the lights off, and even sent a second one to make up for the trouble! Very happy with this purchase! Also, if you want super clicky keys, this is pretty good! If you want it to be quiet, probably find something else. Love it clicky though!

Waste of money.
I bought this one on accident but bought a Bluetooth version of this same item and it doesn’t work with kobo libra color no matter what! This is a waste of money and I would not buy of these items as a page turner!!! They are clanky!! Waste of $40!!!

Works exactly like it should.
I wanted the 2.4 Ghz version for the range and it is exactly what I needed. Can't go wrong with this one.

Looks great, questionable application and connectivity not as expected.
When I ordered this, I was almost positive that it stated having Bluetooth functionality as well as hotswapable switches, but upon reviewing it a few times since, I no longer saw hotswap listed as a feature but still was under the impression it supported bluetooth, which the video preview and included manual confirmed, but upon trying to activate bluetooth mode, found I could not. The included cable is very high quality and alone would be worth $5-10 on Amazon or in a retail environment. The dong is generic but gets the job done, and has little delay, though if you intend to use this for something like Osu, you will want to use wired connection since timing in that game is so precise. The website used to host the software is clearly made by and maintained by a small group, and lacks the professionalism found on many driver websites. Even so, the application itself does what it needs to in remapping the keys though, but I'd much prefer an open source software for such a barebones device. The customization is decent and allows many functions that I see lacking in many keyboard customization software, like macro keys, single-press or multi-press holds, and media key functions. The main concern with a closed-source program is that something keyboard related can intercept keys and be a backdoor keylogger, so knowing the origin of the software would be far more reassuring than the website they want you to download from. Due to my misconceptions (which may or may not be due to a description change), the first thing I tried was connecting to bluetooth, but no combination of button presses and holds would activate bluetooth mode (which the included manual stated is a hold of the connect button and the keys turn red). So due to the lack of BT, this is not Android or iOS compatible, not without a dongle at least, diminishing the versatility of this device. Also due to my misconceptions, I tried hotswapping the switches, which appeared to be possible as a similar amount of force pulled the key switches out completely like I'd have on a decent keyboard and without removing solder, leaving a gap for the new switches to fall into, but upon installing new switches, it appears that this is not a feature and I ruined the device. If you intend to use this wired, or with just the dongle, it is decent, the included switches are fine, but as someone who prefers silent tactile and linear switches over clicky switches, I do wish there was a choice to customize this before buying and more so hotswappable after buying. For the price, it's not bad though.

Great for gamers and productivity fans, but wish I had the Bluetooth version...
With various systems on my desktop, I wanted a way to lower, raise and mute the volume quickly and maybe have a way to initiate tasks with a keystroke. I sometimes use a keyboard with multimedia controls and sometimes use an eMeet Mute device, with an emphasis on "sometimes." For other times, this configurable 3-key pad fits the bill. It comes with a nice USB-C 2.0 cable and a 2.4Ghz wireless USB connector. Although the instructions include details on using Bluetooth, my model doesn't include that, unfortunately. But the 2.4Ghz wireless connector works with a KVM adapter, so I should be able to use with multiple systems. I was able to switch between 2 systems using the USB and 2.4GH wireless connections. Nice! The keyboard seems well made, and the keys have a loud click. They keys are not hot-swappable, likely to reduce the cost. There are 2 USB-C connectors to allow the cable to be behind or on the side. There are small pads under the keyboard to protect the surface from scratches from the device. I'll likely use a Velcro strip to hold the device in place as it is very light and likely to move when using if not secured. The lights only display briefly to indicate the type of connection or low power status, so even though they look nice, don't expect to be able to make a mini lightshow. The Elfkey software by PC Sensor seems sketchy, but seems to work very well and in an intuitive way. In order to use the software, the device must be connected via USB. According to the useful Elfkey User Manual (PDF), once you save the key configuration, you don't need the software to be active - unless you use a one-click open function, which allows you to open a folder, file or URL. There are MacOS and Windows versions (as of 2023 Aug 29), with a Linux version "coming soon." I used only the Windows version. The functionality, ease-of-use and construction quality at a competitive price make this a win for my specific use case.

Will break quickly
1/3 keys completely stopped working, I got the keypad 3 months ago. This is the second one I've purchased, hoping the issue with the first was a fluke. Don't buy.

una svolta il software in dotazione permette di personalizzare ogni tasto, anche con combinazioni di tasti o azioni specifiche. . io la uso con il ctr+C il ctr+V e con INVIO ed è comodissima la batterie dura svariati giorni e comunque è utilizzabile durante la ricarica

Funktioniert! Nutze das Ding über 2.4 g mit dem USB-Stecker. Für die Software den QR-Code auf der Rückseite von dem Ding scannen. Bitte schön!

wirklich gute Ausführung, qualitatives USB C Kabel mit dabei-> mit stoff überzug, nicht son billiges plastik teil! setup ist gut und schnell mit kleiner anleitung erklärt hat jetzt keine großartig wertvolle verpackung, aber darauf kommts glaub ich eh ned an :) Es ist wie, als hätte man ne kleine baby tastatur neben seiner normalen - die Tasten sind sehr clicky, was ich auch sehr mag (ist aber wahrscheinlich nicht für jedermann was)

Il bluetooth non sembra affidabile (non rimane connesso al PC per più di qualche secondo) ma con la sua chiavetta funziona perfettamente, tanto io lo userò sempre così e quindi non ci sono problemi.
