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.

We tested the Mountain Everest Max fully assembled as if we were testing a normal full-size mechanical keyboard. Since the keyboard is using Cherry’s original MX Red switches, the outcome of this testing was unsurprisingly predetermined – Cherry is known for their strict quality control and we consistently receive the same great performance results from testing keyboards using their switches.

The force disparity is below ±3%, reflecting the exceptional quality control we are used to receiving from keyboards with original Cherry MX switches. The average force at the actuation point (not the maximum pressure point) is at 43.6 cN, nearly perfect for a Cherry MX Red switch.

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, yet I do not find linear switches like the Cherry MX Red to be uncomfortable either. The lack of both tactile and audible actuation feedback may not be ideal for professional use but the Cherry MX Red switches of the Mountain Everest Max were very comfortable for long-term use. Despite its full-size keyboard shape, using the Everest Max did require a short learning curve, as the gap between the arrow/command keys and the rest of the keyboard is slightly narrower than that of a typical keyboard.

Gamers will be the ones to fully appreciate the layout and features of the Everest Max. The Cherry MX Red switches are very comfortable for long gaming sessions and the snappy modularity of the keyboard allows for the seamless removal of the Numpad every time more desk space is required for the mouse.  Online gamers and streamers will appreciate the extra display keys, while advanced gamers will enjoy the flexibility of the Basecamp software. The only negative aspect that we found irritating was that we had to select the volume submenu on the display dial every time we needed to adjust the volume, as the display keeps resetting back to its main menu after a few seconds. We suspect that the company will soon remedy that with a firmware/software update.


Mountain is making a huge statement with the release of the Everest as their first keyboard, yet they are also taking a huge risk by reaching for the top with their very first attempt. Most newly founded companies, or even companies that attempt to diversify, usually try and take a piece from the largest segment of the relevant market, and only after that work their way up. Mountain took the entirely opposite approach with the release of the Everest Max, as the keyboard is aimed entirely towards hardcore enthusiasts that pay little attention to price tags, and who are the smallest segment of the peripherals market.

Undoubtedly, the company’s engineers placed a lot of effort into the design, materials, and manufacturing of the Everest Max. It is one of the most well-made keyboards that has ever found its way into our labs, with a flawless finish and very durable construction. Despite its modular design, the keyboard is exceptionally sturdy when fully assembled. We also have to take into account that this is the first keyboard we have tested that features original Cherry MX switches which can be removed/exchanged by the user. This makes the Everest Max practically unbreakable, as users can easily swap switches that may go bad from mistreatment and/or overuse. Our only complaint lies with the top surface of the rotating dial, which can be scratched a bit more easily than one would expect from a screen on such an expensive device.

As far as mechanical keyboards are concerned, unique features are rare nowadays, as the market is saturated with hundreds of products. None the less, Mountain managed to give the Everest Max a touch of uniqueness with the programmable display keys and the multifunctional rotating dial. The Basecamp software makes the Everest Max a very versatile keyboard, allowing users to customize its functionality and aesthetics to their every whim.

The Mountain Everest Max is a unique keyboard, unlike any other currently out in the market. However, its $199 retail price is several times that of a more basic keyboard, a fact that will definitely drive most users away. The Everest Max is a keyboard meant for the elite – users that want to have an excellent, unique keyboard unlike any other and are willing to pay a grand price tag for it. Although the $119 Core version of the Everest is nearly half the price as the Max, the Core is not really competitive as a stand-alone tenkeyless form mechanical keyboard. On the other hand, the Everest Max may be very expensive but it does have many unique features that could draw the attention of users who are seeking a well-built keyobard that is way above the norm.

    The fact that the keyboard is milled *at all*, vs. cast, stamped, or (worst and most common) injection-molded plastic, is the point.
    The fact that the finish is left such that you can easily tell it is made of machined metal is similar to exposed carbon fiber vs. painted carbon fiber. It's a flex.

    Meh! To those of us with manufacturing g experience there is no excuse for unfinished tool marks. There is tooling that makes finish swirls or circles. There is no reason to leave it this way. I would be embarrassed if someone pointed this out to me from something I did. But I would never allow it.

    You realize that injection molds for something like this one piece can easily cost tens of thousands of dollars? If the assumption is that this was CNC/d, then this finish is abominable.

    God you mechanical engineers are literally the worst... machinist here, that's quite obviously an intended finishing pass, and if you don't know the visual cues that tell you that from these photos then I highly doubt you have real 'manufacturing experience'. In fact, the idea that you even considered the possibility that this would be a molded part already tells me that. Just because it's not to your taste (or mine) doesn't make it a mistake, however hard you want to believe that you know more than the guy running these in a VMC. Get over yourself. Reply

    Please, you guys just do what you’re told to do. Engineers don’t make the final decision either unless the run the company. I have experience because I was a partner in a manufacturing concern, and I’ve designed and built machines and electronic products. I still have wood and metal working shops.

    This is a typical machining step that we do inside parts all the time. It’s not meant as a finishing step. These people used it as such. I don’t really mind, and wouldn’t have even bothered to comment, but the article said is was a decorative finish, which it isn’t.

    Yes, they are using it that way simply because it’s exposed to the customer. The reason I mentioned molds is simply because, as you didn’t understand, in small runs, which these keyboards could very well be, molds are very expensive—if they had decided to go that way. How many of these will they sell? Hundreds of thousands? No. Tens of thousands, I’d bet not. Thousands possibly. But if it doesn’t prove popular, it could be hundreds. And, more importantly, I was responding to the above post where p,attic and molds was mentioned.

    Oh so you’re not even an engineer, got it, didn’t think it was any possible for you to be less intelligent but apparently so… if you think even roughing passes should leave tool marks like this then you know even less about machining than I thought. I’ve done a hundred jobs with a plain class 7 finish for every job with one of these finishes, but it is a specific finishing technique and I can recite the speeds and feeds for it to you from memory, even though it would be completely wasted on you.

    You seem to be getting hot and bothered by an honest disagreement. Once you resort to personal insults, you have lost.
    I like the finish, whether or not it is generally intended as a finish, but I don't think melgross's posts were unreasonable, and certainly not worth this kind of behavior.
  • ceeb285 - Monday, November 22, 2021 - link

    Sorry Sivar, but when melgross made a completely unprompted comment falsely (objectively and demonstrably falsely, at that) accusing all of the people behind this product of sloppy workmanship, that is unreasonable and downright insulting. I realize it's not so uncommon for Anandtech commenters to falsely paint themselves as experts, but it doesn't make it any less disgusting whenever it happens. Reply

    I actually own this keyboard and can confirm that the milling marks are cosmetic. You can't really see it in the review sample but at the edges of the plate, the circular marks don't overlap in the north-south direction.
    i.e. The mill was run along the east-west direction, lifted, moved north-south, and then run along the east-west axis again. This wasn't a leftover from the material removal process.
    As to whether this patterning is appealing or otherwise would be more of a personal preference - personally, I don't mind it.

    This is what it looks like when the milling marks are left in an appealing way instead of a cost-savings way.
