DrunkDeer A75’s Features

One of the highlights of this gaming keyboard is its unique magnetic Hall effect switch. Unlike conventional mechanical keyboards, the DrunkDeer A75 doesn’t rely on a physical mechanism within the switches. Instead, it uses a magnet and a Hall effect sensor to measure the magnetic force and determine the actuation point. This system allows users to adjust the keyboard’s actuation point between 0.4mm and 3.6mm.

The result is an incredibly smooth typing experience, with a satisfyingly solid clack and none of the hollowness you’d get from cheaper mechanical keyboards. When typing on the DrunkDeer A75, it’s easy to see the effort that has been dedicated to the hardware side of things.

The Keyboard’s Software

Unfortunately, the software accompanying the DrunkDeer A75 fails to live up to the high standard set by its hardware. The DrunkDeer Antler (shows as Keyboard OEM Driver when installed) application can be somewhat hard to use at first, but it’s web based and it gets the work done.

Rapid Trigger Feature

Rapid Trigger is an innovative functionality found in magnetic switch keyboards. It’s also present in specific Wooting, Razer and Steelseries keyboards.

By dynamically adjusting the actuation point during a keypress based on travel distance, this feature optimizes key activation and deactivation. In simpler terms, it ensures a key is activated instantly when pressed and deactivated immediately upon release, removing the usual latency tied to switch movement, which can sometimes be more than 50ms. This is particularly advantageous in games demanding quick actions and responsiveness.

Enabling Rapid Trigger on DrunkDeer Antler

  1. Set Action Point: Under the Sensitivity menu, choose the key to adjust and set the initial action point, with a range of 0.4mm-3.6mm.
  2. Activate Rapid Trigger: Elevate the sensitivity setting above 0 to turn on the Rapid Trigger function.
  3. Adjust Other Keys: For each additional key you want this function enabled for, repeat the first two steps, then hit save to store these settings. The rapid trigger sensitivity can be tweaked within a 0.2-3.2mm range.

Games Enhanced by Rapid Trigger

  • FPS Games: Titles like Valorant, CSGO, and Apex Legend benefit significantly from Rapid Trigger. It boosts in-game actions, such as aiming and shooting, by offering enhanced movement precision and quicker response times.
  • Rhythm Games: For games like osu!, the Rapid Trigger feature can improve your hit accuracy and rhythm synchronicity. It allows players to align hits perfectly with the rhythm while also diminishing finger strain.

Verdict: Great Hall Effect Keyboard but…

In summary, the DrunkDeer A75 offers a fantastic typing experience and highly responsive keys , thanks to its innovative hall effect switches. However, its full potential is held back by a weak software offering. At its current price point, it’s a relatively affordable magnetic keyboard that’s great for typing if you like steep keys.

Overall Rating: 8/10


Smooth typing experience: Even without using the accompanying software, the keyboard itself is enjoyable to use.
Hardware potential: If the software improves, it could unlock the full versatility and responsiveness of this board.


❌ Plastic case. You might want to go for a A75 Pro with aluminium case which also got some weight and better build quality.
