Per-Key Quality Testing

In order to test the quality and consistency of a keyboard, we are using a texture analyser that is programmed to measure and display the actuation force of the standard keyboard keys. By measuring the actuation force of every key, the quality and consistency of the keyboard can be quantified. It can also reveal design issues, such as the larger keys being far softer to press than the main keys of the keyboard. The actuation force is measured in Centinewton (cN). Some companies use another figure, gram-force (gf). The conversion formula is 1 cN = 1.02 gf (i.e. they are about the same). A high-quality keyboard should be as consistent as possible, with an average actuation force as near to the manufacturer's specs as possible and a disparity of less than ±10%. Greater differences are likely to be perceptible by users. It is worth noting that there is typically variance among keyboards, although most keyboard companies will try and maintain consistency - as with other reviews, we're testing our sample only.

The machine we use for our testing is accurate enough to provide readings with a resolution of 0.1 cN. For wider keys (e.g. Enter, Space Bar, etc.), the measurement is taking place at the center of the key, right above the switch. Note that large keys generally have a lower actuation force even if the actuation point is at the dead center of the key. This is natural, as the size and weight of the keycap reduce the required actuation force. For this reason, we do display the force required to actuate every key but we only use the results of the typically sized keys for our consistency calculations. Still, very low figures on medium sized keys, such as the Shift and Enter keys reveal design issues and can easily be perceptible by the user.

As expected, the SteelSeries QX2 mechanical switch is an almost perfect copy of the Cherry MX Red switch. We say "almost" because the switch does have the exact same travel, actuation point, and force-to-travel graph, but the QX2 switches are not nearly as consistent as Cherry MX switches are. The switches have an average actuation force of 44.8 cN but the disparity is high, at ±8.64% across the main keys of the keyboard. It is not too high a figure and we suspect that the vast majority of users will be unable to tell the difference by touch alone. On the other hand, Cherry MX switches usually display a disparity of about ±3%, so the difference is more than just measurable.

Hands-on Testing

I always try to use every keyboard that we review as my personal keyboard for at least a week. My typical weekly usage includes a lot of typing (about 100-150 pages), a few hours of gaming and some casual usage, such as internet browsing and messaging. I personally prefer Cherry MX Brown or similar (tactile) switches for such tasks. The SteelSeries QX2, which essentially copy the Cherry MX Red switch, would not be at the top of my preferences list but I do find such switches comfortable and easy to be accustomed to. True enough, I found the SteelSeries Apex M750 quite comfortable for long typing sessions, especially when I was forced not to take a break for over an hour. The only complaint I would voice here is that the keycaps wobble a bit and the feeling is, at times, awkward.

For gaming, Apex M750 is hardly any different than another mechanical keyboard on its own. It is the SteelSeries Engine 3 software that makes all the difference. After programming a couple of profiles for my test sessions, in which profiles I reprogrammed a few keys and disabled others, the gaming experience was fantastic. The only issue is that a main key of the device has to be sacrificed for each macro/text command. This is a major problem for MMORPGs, as reprogramming any of the main keys will cause issues with the in-game user experience (i.e. it is impossible to type a message to a friend if your keyboard's keys have been reprogrammed to macro commands).

    So hold on, is menu button completely gone to be replaced with their Fn key equivalent?
  • wavetrex - Saturday, September 8, 2018 - link

    Yes, there is no "menu" button.
    Which I found inconvenient as well, but resolved it quickly by remapping the right "Windows" key to be the "menu" button".
    The "Steelseries" key cannot be remapped, but every other one can.

    This is an absolutely excellent keyboard and I've been enjoying it since March 2018, and to this day nothing else to complain about it.
    It looks great, works great, easy to maintain (clean), software is awesome (and could be improved even more).

    Thank you. that seems like a decent compromise, I do use left winkey as well as menu (a lot), but can't recall many cases where right winkey would be in use.

    @E. Fylladitakis
    Some people (that includes myself) like and want the minimalist design, which still keeps full ANSI compatibility.
    I bought this keyboard especially for this, it has the minimum size for a full-104 key keyboard and fits my desk well.
    Other mech. keyboards might have extra functions, dedicated media or macro buttons, but they are also significantly BIGGER, and that becomes a problem for many people.

    The position of the media combo-keys make it easy to distinguish between "Play/Pause - F8" and "Next - F9", since there's that gap between them, and these are basically the most useful ones.

    Volume Up/Down are also well placed, at the end of Fn row, making them easy to find blindly.

    Finally, you seem to have missed in your article the fact that lighting can be controlled through the keyboard itself as well, not just the software.

    Pressing "SS Key" + Print screen / Scroll Lock / Insert / Home / Delete / End changes lighting modes and adjust parameters (like color, speed)
    Even without installing the software, it's possible to switch to a more "pleasant" lighting, like "Starlight" mode. The keyboard remembers the last setting event through power-off, so moving it to a computer without the software installed is nice.

    There is no need to try and justify your purchase to anybody. Every product has a potential market - if it didn't have any potential at all, nobody would bother reviewing it anyway. I am just highlighting what I think it is important, from my point of view. Readers are free to decide themselves whether the product fits their wants and needs.

    About this however:

    "Other mech. keyboards might have extra functions, dedicated media or macro buttons, but they are also significantly BIGGER, and that becomes a problem for many people."

    That's not even remotely true. There are at least a dozen mechanical keyboards available with dedicated media keys/volume control knobs which are not even bigger than the M750. The dead space occupied by the company's logo would be enough to host at least dedicated volume controls.

    Finally, that's a gaming keyboard and its target group is, well, gamers. I really don't think that a gamer cares about being able to switch to "starlight mode" without the software if plugging in the keyboard to another computer. I just never fathomed that someone would buy such an expensive keyboard for that feature. But thank you for pointing that out, just in case someone actually does care about that.

    Sad how badly Ian Cutress has run this once great publication into the ground. Irrelevant, boring articles combined with endless keyboard reviews....ladies and gentlemen, I give you the result of liberal millennials "at work"
  • m16 - Sunday, September 9, 2018 - link

    It just so happens that the majority of people happen to use keyboards and there's a lot of new offerings showing up.

    If you want to talk about drivel and politics, there's a place for you, fox is elsewhere on the internet, and it includes retirees.
  • imemerson - Sunday, September 9, 2018 - link

    This site still does amazing work, including reviews of keyboards which are the most important peripheral for any computer. To make this site more useful to those of us that are here to learn and use it correctly, please remove yourself. I'm sure you can find plenty of low-quality "liberal millenials are ruining everything" places to spout your nonsensical drivel (try InfoWars or anything under the label of Fox News) and please stop slandering a site that actually engages in high-quality reviews and writing with a long history of excellent and truthful reporting.

    "Sad how badly Ian Cutress has run this once great publication into the ground."

    Hey, credit where credit is due. I'm the editor-in-chief, I am the one who's running it into the ground! =P

    But in all seriousness, if you have specific concerns about the site I'm more than happy to hear them.

    However as far as keyboard reviews go, I am very satisfied with them and intend to continue. They are a nice way to mix things up in terms of content, and they draw reasonable traffic and reader interest.

    What's been irrelevant and boring recently? Lots of investigative work and new launches, as well as extensive show coverage in the past few weeks
