Epomaker TH40 Review
Gasket-mount typing feel

One of the biggest features of the Epomaker TH40 is its “gasket mount.”
This is a mechanism where gaskets installed inside the keyboard absorb vibrations during typing, realizing a quiet and soft typing feel.
It is less tiring even after long typing sessions, and its high silence means you can use it with peace of mind even in quiet environments like cafes or offices.
Mr.GadgetsI definitely want those who like a “soft typing feel” to try this out!
The variety of connectivity is super convenient!


The “Epomaker TH40” comes with three connection methods: USB Type-C wired connection, Bluetooth 5.0, and 2.4GHz wireless dongle.
Because of this, it can easily connect not just to desktop PCs, but also to mobile devices like tablets and smartphones.
This is an extremely convenient specification for those who want to set up a wireless environment.
Mr.GadgetsFor people who use multiple devices while switching between them, this is a major appeal!
Free customization with hot-swapping
The TH40 adopts a hot-swap PCB that supports both 3-pin and 5-pin switches, making switch replacement very easy. You can change to your preferred switches without using tools, so even those new to customization can feel at ease.
Mr.GadgetsThe fact that it can be easily customized is a great point!

A layout that is easy to use despite being compact

Because 40% layout keyboards have fewer keys, some might think they “seem hard to use.”
However, the TH40 is equipped with programmable layer functions, allowing you to freely assign the keys you need.
For example, by setting arrow keys and function keys to a layer, you can achieve space-saving while maintaining the normal operational feel. Using the VIA software, even beginners can easily change the settings.
Ms.GadgetsIt takes a little getting used to at first, but if you master it, your work efficiency will jump significantly!
Mr.GadgetsWell, it is tough until you get used to it though
Reliable wireless use with a large-capacity battery
Since it has a built-in 3000mAh battery, it can be used for a long time even when connected wirelessly.
It is perfect for working on the go in 2.4GHz or Bluetooth modes.
Charging is done via USB Type-C, so it is also convenient that you can charge it with the same cable as most other devices.
Mr.GadgetsIf you are considering wireless operation, this battery performance is quite attractive!
Summary
I felt that the Epomaker TH40 is an excellent keyboard that does not compromise on functionality or comfort while maintaining the space-saving nature of a 40% layout.
Ease of use is pursued in every aspect, such as the soft typing feel of the gasket mount, the abundance of connection options, and the high level of customizability.
Mr.GadgetsWell, it takes practice to master it, and the ultra-compact 40% layout is not for everyone
Ms.GadgetsAll in all, you could say that the Epomaker TH40 is a keyboard that truly shows its worth to those who understand the characteristics of a 40% layout and have the leeway to enjoy customizing it to match their own work environment and usage!
