After downsizing to a TKL a few years ago there were more than a few times where I missed having the numpad so when I saw the layout on the Redragon Pollux, and the fact that it had standard hot swap sockets, I was sold. The functionality of any missing keys are accessible by holding the function key and pressing the key they've mapped that function to. The placement of these remapped functions is intuitive and easy to remember, but if you need to use the F row keys without taking your other hand off of the mouse then this probably isn't the keyboard for you. They've also conveniently mapped media key functions like volume and pause/play to the Z-M keys. The only thing that's outright missing from a full size keyboard is the second enter key.
It comes with Redragon branded red linear switches which felt way better than I expected. I liked the switches from my old keyboard so I just swapped them in but the stock switches felt good too. Unlike most Redragon keyboards, this one has north facing standard 5 pin hot swappable sockets which means you can install switches from other switch manufacturers like Cherry, Gateron and Kailh. The RGB LEDs stick up a bit from the PCB so they recommend using switches with the little cutout for the LED on the bottom, but even V2 Zealios (which don't have that cutout) snapped in without a problem.
The plate mounted stabilizers are pretty loose and will need some level of modification to fully eliminate the rattle. Honestly, I've heard worse from more expensive keyboards but there is definitely a lot of room for improvement. Since the board is hot swappable, you could also install enthusiast grade plate mounted stabilizers if you wanted.
The keycaps are the standard double shot ABS shine through caps that come with most gaming keyboards. The mapped functions are printed in white on the top of the keys, which isn't the cleanest look, but isn't a deal breaker. If you want to put different keycaps on it then you'll need to find a set that includes the smaller right shift and right modifier keys as well as the small 0 and + for the numpad.
The RGB backlighting is vibrant and animates smoothly. There are about 20 modes to choose from including the expected ones like the color wave and spinning color wheel. You can cycle through them by holding FN and pressing the right alt key. Holding FN and pressing the arrow keys controls the brightness and speed. Holding FN and pressing the space bar will allow you to cycle through single colors for modes that allow it. Pressing FN and backspace will toggle the backlighting on or off.
There are tiny red LED indicators for caps lock and num lock on either side of the 2 key on the top row. They're recessed enough that they're visible but don't interfere with the rest of the RGB lighting. I've included a picture with my review so you can see what it looks like. You can lock the windows key by pressing FN+Win and the Win key will light up white (more of a purple tinged white because RGB keyboards struggle with pure white backlighting) to indicate that it is locked.
There is downloadable software you can get from the website on the box but I never bothered with it because you can do everything except program macros directly from the keyboard itself.
The only real annoyance I have is that the detachable USB C port is on the left side of the keyboard and the included USB C cable isn't a right angle plug so it sticks out further than I would like. Since it's detachable I can buy a right angle cord if it still bothers me later on.
For around $60 you're getting a unique layout that actually balances form and function in addition to a path to further customization if you choose to take advantage of it.
