Mechanical Keyboard Review: Kumara Red Dragon K552

Posted: June 17, 2017 in keyboarding



Yet another in the growing group of inexpensive mechanical keyboards, the K552 is manifestly similar to a few of the others I’ve tried. It is a tenkey-less model that uses a metal top plate and floating keys. The switches are Outemu blues, and they feature single color backlighting, red color only. Key caps are double-shot ABS. There are nine levels of brightness available for the backlights, as well as fully off. As I’ve come to expect from this type of cap, the contrast isn’t the strongest with the backlight all the way off. In a normally-lit room, however, it should be sufficient to locate the letter you’re looking for, or the home row.

None of the brightness levels are overly intrusive. Even the lowest of the illumination settins works to significantly improve legibility. The font featured here on the key legends is about what you’d exect. A bit “gamer”, but useful enough. I’ve mentioned before all these backlit keys seem to be manufactured by the same few companies, or at least to a similar standard.

The structural rigidity is significant. Unlike some of the other models in this price range, the K552 features a one-piece plastic under-tray that exends all the way around the sides and beyond the surface of the top plate. This adds a more substantial feel to the keyboard. The flip up feet have a rubber traction wrap on them, wich is appreciated.

In Use:

If you’re familiar with the blue switch ‘board, this one provides the same typing feel as others of its ilk. It has the Outemu switches, which I’ve found to be just a bit heavier and more tactile than other Cherry-based switches. As well, they seem to have a bit crisper click sound. I’ve very close to calling the Outemu switch my favorite of the clones in the blue type. I like them fine, and think they’re a great value for the money. The noise will be an issue in a shared environment, so prepare yourself for that.

Kumara makes a brown-switch version of this same ‘board, so that might be the better choice to lower the noise level down a bit. My undersanding is that the switch type is the only difference. There are also other versions of the ‘board that feature no backlight (even less money), multiple color LED (non changing), and RGB programmable LEDs. The RGB is, of course, more money as the addition of the more expensive LEDs will add complexity and material cost. Even the most expensive version is less than $60 at current prices (Spring 2017). Because the RGB feature is not important to me, but is a feature that others are interested in, the value of these various versions is subjective. For reference, the single color backlight is about $35 at this time. The non-lit version is under $30, if maximum value is your watchword.

The K552 is a good typing machine, and feels very solid under your fingers. It has no sag, squeak, or other unaccountable mechanical sound during the typing process. Since I didn’t mention it before, the device arrived in perfect condition, and everything works as expected. The small lip around the outside of the key block doesn’t quite function as a bezel, but it gives a little protection to the floating keys, such that impacts from the side are less likely to bear upon the outside perimeter as heavily. Think of it as sort of a meta-bezel.

At this point, I’ve become altogether familiar with the 87 key layout, and don’t really find it to be an impediment at all to my work. I don’t do a lot of numerical entry, however. If you’re all about the Excel spreadsheets and data entry, you’ll want to shop for a ‘board with a numeric keypad. They are out there, and often just a small amount higher in price than their TKL competitors.

As with other blue switch ‘boards, this will likely not provide any significant advantage for gaming. Depending on your preference, you might find it slightly stiffer than you’re used to, but no blue switch is ultra-stiff, so you needn’t worry that it will be unworkable for the average typist.

Because everything about the layout is standard, you have no adaptation to do in terms of reach and spacing. ANSI layout is maintained right down the line. There are function layer commands for things like media control and auto-launching some Windows features, like the calculator. The LEDs can be turned up and down with this FN key command layer, as well. All is as expected.


All in all, you get a solid and useful keyboard for your money here. I wouldn’t say that it is particularly stunning looker, but it is a “quiet” enough design that you have some dress up options at your disposal. Because of the raised “Redragon” logo panel, it would take a bit of work for you to arrive at an altogether custom appearance. You could sand down the logo and repaint the top plate a different color, but that is a bit more work than you may want to do.

The red LED will be something of a limiting factor for key replacement, as you’ll want to make sure that you select alternate key caps that will go well with the red lighting (unless, of course, you plan to simply turn the LEDs off altogether). If your key caps are altogether opaque, the red light will still propagate from beneath the keys. Of course, if you have a keyset designed for backlighting, that will do just fine. I may re-cap this keyboard when I have some caps in hand with which to start a project. I’ll touch base with the results.

Usage Case:

I see this is a nice option at the cost. It goes for about what the Drevo Tyrfing and a few other keyboards cost. I still feel that, for customizing, the Tyrfing is one of the best options. That said, it has a particular acoustic component that may not be to everyone’s taste. The Kumara provides a nice option, and I think that it would serve well. I believe that it is a step up on fit and finish as well as build quality, when compared to the cheapest mechanicals.

For a home user or someone in a situation where typing noise is not a factor, this offers a lot of performance for the dollar, and may also serve as a an interesting option for a “project ‘board”. For someone looking to dip their toe into the waters of mechanical keyboards, or someone who wants a device that they can try customizing without worrying about ruining a very expensive device, this could be the very thing.

Out of the box, it provides good tactility and audible feedback, looks fairly nice, and has a sturdy feel. That’s a lot to get for less than forty bones.

Cheers, and happy typing.
