After trying a mechanical keyboard it is impossible to go back to a membrane one, and for good reason, the feel of the switches is unmatched, but obviously it is better in some models than in others, so it is time to detail each offer before being able to arrive at one purchase decision. This time we’ll be looking at a great value proposition, the GameSir GK300, a mid-range wireless mechanical keyboard offering that provides an excellent general-purpose experience for half the cost of a similar keyboard from a bigger name brand. . 

But as with almost everything in life, there is a catch, and that is that it is not particularly good for gaming due to its switches, since we are dealing with imitation blue switches. Despite that important detail, it’s still a respectable option with all the features and extras we’d expect from more expensive keyboards. And if you are wondering, the answer is yes, it has a backlight, something that cannot be seen very well in the images. 

If instead of a keyboard what you are looking for is a wireless controller to play on PC or Android, you may be interested in taking a look at the GameSir T3 .

This is the GameSir GK300 

The GameSir GK300 has a run- of-the-mill 108-key layout with a numpad, and as a bonus, its switches and keycaps are standard, meaning it’s compatible with almost all Cherry-style mechanical key sets. Being full size it is obvious that it will be a bulky product, measuring 43.78 x 12.90 x 4.19cm and weighing close to 1.4KG.

It has an ergonomic design with a 7.5° degree tilt to accommodate the user’s posture. Another element that we can thank is the presence of a resistant aluminum alloy plate on the upper part of the body, which gives a premium feel and finish to this keyboard. 

Something we don’t see every day in this price range is the wrist rest on the bottom of the GameSir GK300. This is extremely comfortable and also offers the option to undock if we prefer.

Keys, lighting and ergonomics 

Unfortunately there is a big but with this keyboard, and that is that the switches are not original Cherry blue , they are imitations made by TTC and the company is totally transparent with it. This isn’t to say they’re bad switches though, they still offer the satisfying typing feel and sound associated with mechanical keyboards, but there is a slight wobble to the key action that might deter purists accustomed to mechanical keyboards from high-end. 

With an actuation force of 50g±20gf and an actuation point of 2.2±0.6mm , they’re clearly not the best keys for gaming, but they do their job in all other areas and for a $80 keyboard or less, we will hardly find something better.

Moving on to the backlighting, it’s important to make it clear at once that there is only white lighting on this keyboard, which is fine, not all of us are looking for RGB lights with wacky patterns to show the world how gamer we are, some of us like it simplicity, minimalism and functionality over aesthetics. The real purpose of the backlight is to keep the keys visible at all times, and in this regard the CK300 does the trick. 

That said, the LED lights offer 5 levels of brightness that we can select in combination with 3 light patterns : wave, static and breathing effect. Similarly, we can choose to turn off the lights entirely.

The GameSir GK300 allows us to choose between a 2.4 GHz connection via dongle or Bluetooth via the power switch above the numeric keypad. It is important to note that in the case of the first option the delay is only 1 millisecond, while in the case of Bluetooth it is 8 milliseconds, so we already know which is the best of the two. 

The presence of two wireless connectivity options also means the keyboard can switch between two machines or mobile devices on the fly; which is a small incentive that we can thank. 


On the other hand, the keyboard’s charging port is an awkward and outdated Micro USB. We say uncomfortable since it is located on the left edge instead of the top, which could be annoying if we touch it when pressing the escape, tilde or tab keys; and if we use the mouse with the left hand, even worse. 

It should also be noted that the charging port and cable are only for that purpose, we will also need to have the keyboard paired via Bluetooth or dongle to be able to use it. 


The 3,600mAh internal battery provides the GameSir GK300 with 300 hours of battery life, more than enough for a week of use, but that’s only with the backlight off . If we decide to keep the lights on at all times we can expect 30 hours of duration in the best case. Finally, the charging process takes about 3 hours. 


We found it for sale in the always reliable and also in for an affordable price.
