The Kailh Red is a light linear, Cherry MX Red clone switch. It has two variants with different part numbers, PG151101D05 and PG151101D93. The latter supporting RGB lighting according to their website. There are no other documented differences between the two, though this review will focus on the PG151101D05 variant.

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

Smoothness: 4/10

On-centre keypresses are scratchy when pressed slowly, but when pressed quickly, it ‘disappears’.

Off-centre keypresses are very scratchy accompanied with occasional binding when typing at speed, especially on longer keys. There are MASSIVE weighting inconsistencies between the switches which often results in a lot of misspelt words.

Overall, unless you’re a prefect typist, these will not suit you, or most people for the matter. I would personally stay away from these if you’re after a smooth experience.

Weighting: 4/10

There is roughly 1.9mm of pre-travel, with the switch actuating at 50g at 2mm and a bottom-out force of 66g at 4mm of total travel. Essentially, it is very similar to the Cherry MX Red switch which I find too light for my taste, but a lot of people enjoy this weighting. However, as mentioned above, the switches have weighting inconsistencies when typing at speed.

Sound: 5/10

Sound is average at best. If the switch wasn’t as scratchy and inconsistent, it would sound a lot better in my opinion. Lubing these could help it out a bit though.

Typing Performance: 4/10

The scratchiness isn’t as bad as the weighting inconsistencies, as the scratchiness ‘disappears’ the faster you type. Although, be prepared to make a ton of spelling mistakes when typing on this switch. I think you’d have a higher accuracy typing on a regular rubber dome keyboard.

Gaming Performance: 4/10

For slower paced games such as stealth games, walking simulators or for games where keyboard input is minimal, it’s fine. However, it is no good for faster paced games such as TF2 or DOOM. The switch actuation becomes very difficult to judge due to its weighting inconsistencies resulting in a loss of concentration which is very off-putting. The switch constantly reminds you that you’re using really crappy switches and that you should upgrade to something better.

Final Score = 21/50 (42%)
