The Flashquark Quark linear switch comes in two spring variants – 62 and 68 grams. The springs used are Flashquark’s own Two-Stage Long Switch Spring.

The one I have for review is the lighter 62g variant.

If you’re looking for a smooth, consistent and reliable mid-tier linear switch. This is a very compelling choice.

Just in terms of performance, it competes with the Momoka FROG Linear switch. However, it’s also reminiscent of SP-Star Polaris Grey.

Smoothness: 8/10

On-centre keypresses are very smooth with only minor scratchiness at slow keypresses.

Off-centre keypresses are also very smooth with only minor scratchiness and slight binding at slow keypresses. However, these are barely perceptible in normal typing speeds.

Overall, it’s a consistently smooth switch and I wouldn’t hesitate recommending them.

Weighting: 6/10

According to Flashquark, these switches bottom-out at 62g with a total travel of 3.5mm. Although, a heavier 68g variant is also available.

Additionally, these switches are using Flashquark’s own springs. More information here: Two-Stage Long Switch Springs by Flashquark.

In the real world, the key feel is quite close to the Momoka FROG Linear, so it’s on the lighter side which isn’t to my preference, but these have a cleaner and have a more consistent weighting delivery. It’s one of the very few cases where a dual-stage spring outperforms a single-stage one – This isn’t the full story though.

Consistency wise, it’s very Akko like. It’s a very consistent performer with almost zero binding in most typing speeds. I like it.

Overall, even though it’s a light switch that I personally wouldn’t consider buying, I can at least appreciate it’s top-tier consistency.

Sound: 7/10

If I could describe how these sound in one word, it would be “poppy”. It’s also clacky due to the aluminium case I use, but it isn’t as clacky as other switches like the Akko CS Piano (which are pretty much the “clackiest” switches I know of).

However, the switch installed in my “D” and “X” key make a quiet spring like noise when pressed slowly, but this isn’t noticeable during normal operation.

Overall, they have a nice and clean sound with zero scratchiness. Again, I like it.

Typing Performance: 8/10

Firstly, there’s no way of getting around it – these switches are more often that not, too light for my tastes. Though, I specifically requested this over the 68g variant since I almost always opt to test the heavier variant as that would fit closer to my preferences, but I wanted something different this time around hence I why tested the 62g variant instead, so keep this in mind.

Secondly, as these are lighter than what I would’ve preferred, I began to make more typos than usual, but as these are extremely consistent switches, I didn’t make as many compared to other lightly weighted switches.

Finally, in comparison to the Momoka FROG Linear – it’s closest competitor, the Quark switches are overall a notch better typing performance wise. I’d even consider it a slight upgrade. Plus, the Quark is cheaper (at the time of writing).

Overall, if you’re looking for a smooth switch with a highly consistent and reliable performance, this is an excellent choice.

Gaming Performance: 8/10

Unlike typing, the light weighting didn’t play a huge factor in gaming. In fact, I barely noticed the switch when gaming, both in fast and slow-paced games.

Although with that said, its light weighting was more obvious to me in faster-paced games like DOOM Eternal where keyboard movements are more frequent and require timing which is especially true when using your abilities to their full extent. I’d even go as far as to say that choosing the right switch weighting for you is just as important as its smoothness and consistency.
In slower-paced games like Dishonored 2, the weighting was practically invisible to me. I barely noticed it and I had zero issues with it. However, as I mentioned above this became more obvious in faster-paced games.

Additionally, I also had zero issues when it came to both the smoothness and consistency.

Overall, the light weighting is the only real downside with these. Everything else about them is pretty much top-notch! I highly recommend them to gamers looking for an excellent gaming switch.

Final Score = 37/50 (74%)
