Redragon K585 DITI Wired One-Handed RGB Mechanical Gaming Keyboard, 42 Keys Type-C Professional Gaming Keypad w/Upgraded Hot-Swappable Socket, 7 Onboard Macro Keys & Detachable Wrist Rest

TLDR: Likely the best sub $50 One Handed Keyboard you'll find; decent wrist rest and good thumb button placement, nice weight and non-sliding feet, nearly entirely reprogrammable and hot swappable (see below), and for those who like to void warranties, easily disassembled. It could use a slightly stronger angle, sound dampening (the thin plastic base is pingy) and more robust software, but for the price, you can't really see those as faults.I own more OHKs than I'd like to admit, but I dislike the spacebar on a standard keyboard while gaming (don't like my thumb curled under my palm). This one isn't comparable to the likes of Razer, but for half the price and more buttons, with some DIY, you'll have yourself the best all-around gaming keyboard for under $100.SETUP/USAGE: Works straight out of the box on most anything. The usb-passthrough is a true hub, so it works with almost any (USB 2.0) device, just don't expect it to charge anything. Great for connecting a mouse when using with a laptop lacking ports or Playstation/Xbox (only tried it with a PS4, works as expected). If you have Windows 10, the software allows you to reprogram all but the profile (M1-M4), Function, and recorder buttons. The software is basic but functional. I didn't have troubles with the included braided cable or any other USB-C cable I had. Connection was firm. The base doesn't slide around, but does have a largish footprint. It has more buttons than high end OHKs; too many for straight FPS, but useful for FP/TP RPGs, Mobas, 4X, or any game that needs 'G' or 'T'. The stock switches are decent, if a bit wobbly, the keycaps are thin ABS, but not terrible.ERGONOMICS: I like the placement of the two thumb buttons, but they might be an issue for small hands. The standard staggered keys should make switching from a standard keyboard easy, even if I prefer ortholinear keys. The wristrest is hard but not uncomfortable, and while some may like padding, I find hard surfaces less irritating and sweaty. The additional Map (M) and N and P keys are nicely placed so that nearly anything you need to do can be done with one hand.SOFTWARE: the software is basic and not exactly self explanatory, but isn't hard to work once you figure it out. It only works on Windows 10, and it doesn't allow extended options (you can program any of the main keys to any key on a standard keyboard, media function, mouse action, or a macro; it has profiles (4) but not layers). The changes are saved to the board, so they'll travel with it. You can't do much with the lighting other than change speed, direction, and color of the built-in effects. Still, it's more versatile than the software (or lack of it) found on other low-cost OHKs.MATERIALS/CONSTRUCTION: The main body is, what I assume is, a single piece of ABS. The bottom is the same, as is the wristrest. The top plate is a non-ferrous metal, the switches are plate mounted (3-pin). The stabilizers are part of the body, so not replaceable and made of the same plastic. The keycaps could be better, but expected at this price. Together, it feels solid, and a good balance of weight for stability and portability (other than the size).DIY: beyond the software, most of the keys are also "hot swappable" (the exception being the G2-G5 keys, which seem to be soldered in). The sockets are *not* Kailh, which makes it harder to get the keyswitch in straight, and it has a rather tall LED; you'll need a switch that had a cutout for SMDs (I swapped mine for Akko Blue Oceans because they're available on Amazon and fit just fine). The stabilizers are built in to the plate, so aren't replaceable and are pretty cheap. Lubing helped a bit. Deconstruction means removing the bottom screws (two are under the rubber feet, but as long as your careful, they stick back on just fine),, and then a set of screws to remove the plate/pcb from the base. No foam or gasket, but, again for the price, this isn't surprising. Removing the plate from the PCB means removing all the keyswitches, but with 4 soldered into the sockets this is close to impossible, and then popping some pressure clips. I don't recommend. Since the top and sides are all one piece, I found it easy to paint (in the picture, it's a matte white spray with masked stripes and a clear coat finish). The keycaps are replaceable, but the non-standard "T" and "G" can make finding a set difficult. It worked with several cables I tried from various manufacturers.Overall, this is a great little piece of gaming tech. While not high-end, the ease of use, good button count, and versatility through software and hardware modifications, make this a great choice for an inspiring gamer/builder looking for something to play on and also tinker with, without breaking the bank.

So I have to say, this thing is pretty cool. The build quality is surprisingly very sturdy with relatively heavy plastic. The Blue Switch keys sound great and press well. The magnetic palm rest is really nice. The extra USB port is handy.Couple things to note about the product. The cord is USB C into the keyboard and USB A into your PC. You can program the 7 macro keys (G1-G5, ~ and T) by using the keyboard itself (though only with keys that already appear on this left-handed keyboard), OR you can download software from manufacturer's website that allows you to program ALMOST every key (FN key, Rec key, and maybe one or two others excluded). This latter software method is good if you want to reprogram any of the normal letter keys or if you want to program a key to use a key NOT on this keyboard already (example: Windows key or Enter or any right-side characters or arrow keys). There are 4 layers or modes you can have (accessed via the M1-4 keys), so you can theoretically have a 4 sets of keys programmed. You can set the RGB LED color setting for each layer/mode as a visual clue for what layer/mode you're active on, which is really handy. It does not have a Windows key, which I wish it did, but using the software method you can program another key to be the Windows key (though unfortunately you can't reprogram the FN key for this purpose). The size of the keyboard is larger than I expected, but it's good. The optional key re-programming software is decent. The bottom space key is easily accessible for my thumb. The right top G1 key, though, is not so comfortable for thumb press and I'll need to use my index finger for that one. The top right key (right of F4) is the m character (though a few programs read it like an F5) and I guess has special meaning in some games or something.Overall, this is really quite nice. It can easily be used as a macropad or shortcuts-specific extra keyboard too, which is cool. Have to say, the ~$30 spent on it seems well worth it.
