The Kailh BOX Dark Yellow is a heavier Kailh BOX Black switch and is intended for heavy handed users.

Here’s the video review if you prefer watching content:


The high levels of scratchiness and weighting inconsistencies make this switch very hard to recommend, and especially so for the intended target audience.

I would personally keep searching for an alternative, or spring swapping an already smooth switch such as SP-Star Polaris Grey. Although, that would be quite pricey to do.

Smoothness: 5/10

On-centre keypresses aren’t the smoothest, but they also aren’t the scratchiest. Although, slight levels of inconsistencies are present.

Off-centre keypresses are very scratchy during faster keypresses, but especially more so during slow keypresses. The inconsistencies here can definitely be felt which isn’t pleasant.

Overall, these are quite scratchy and inconsistent especially during off-centre keypresses. I wouldn’t recommend them at all.

Weighting: 6/10

According to NovelKeys, these switches have an actuation force of 70g at 1.8mm and bottom-out force of 80g at 3.6mm.

In my hands, it’s a very heavy switch. Heavier than I would personally like, but I do prefer them over the much lighter Kailh BOX Red. But I’d still take the Kailh BOX Black over these as I found those to be a nice middle-ground between the two.

Additionally, and similarly, I found these switches to also suffer from weighting inconsistencies just like other Kailhua BOX switches. Although, they are more pronounced here with the Dark Yellow.

Overall, these are a bit too heavy for me. Plus, their inconsistent nature makes them even harder to use.

Sound: 6/10

They’re very muted. This is probably due to me not bottoming out on them all the time, but this also makes for a boring, inoffensive sound signature. Don’t get me wrong – it’s not terrible… just boring.

Additionally, due to its somewhat muted sound, you can sometimes make out hints of scratchiness which isn’t exactly pleasing.

Overall, I’d put them just above average. They at least won’t make your ears bleed.

Typing Performance: 4/10

Firstly, I will say that I am a massive fan of heavier switches and this is one of the reasons why I picked these up. However, these were quite a disappointment.

Now, it isn’t the weighting where I am most disappointed about, but rather the scratchiness and inconsistencies. This is possibly the scratchiest and most inconsistent BOX switch I’ve ever used – though this sort of make sense as heavier switches don’t tend to sell many units compared to their lighter counterparts and therefore manufacturers aren’t incentivised to improve on them; this seems like one of those.

So, how does that all translate into everyday typing? Well, simply put… it sucks. It’s not 100% terrible, but they are very unsatisfying to type on. I for one, did not look forward to typing on these and I probably never will.

Additionally, and as I already mentioned, the overall weighting didn’t bother me all that much, but I will say that they are a little too heavy for me. The Kailh BOX Black would be the better choice for between the two.

Overall, the scratchiness and inconsistencies are two of the main aspects that bring this switch down. It needs a revision and it needs it soon.

Gaming Performance: 4/10

Gaming with these is an interesting one.

On one hand, they’re not too bad for slower paced games like Metro Exodus, but these are also the types of games where you feel every switch inconsistency.

On the other hand, they’re far too heavy for any fast-paced action. I certainly wouldn’t want to play Team Fortress 2 using these. Although, when I do, I don’t notice any scratchiness or any inconsistencies at all… just the heavy weighting.

Overall, it’s a weirdly mixed bag. However, I still wouldn’t recommend these for any type of gaming as there are switches out there much more suited to that.

Final Score = 25/50 (50%)
