Epomaker TH99 Pro Review: The Best Mechanical Keyboard for Under $90?
ReviewsThursday, 12 March 2026 at 12:52
The mechanical keyboard market is currently dominated by a drive for efficiency. Users are no longer content with massive full-sized boards that take up half a desk, nor are they always willing to sacrifice the number pad for a tiny 60% layout. This middle ground is where the 1800 layout thrives. The EPOMAKER TH99 Pro enters this space as a refined tool for those who need to crunch numbers during the day and enjoy a responsive gaming experience at night. Priced at roughly eighty-eight dollars, it sits in a competitive bracket where build quality and extra features like screens and knobs are no longer optional—they are expected.

Design and build quality
The first thing you notice about the TH99 Pro is its physical presence. It utilizes a compact 1800 layout, which essentially takes a full-sized keyboard and squashes the navigation cluster into a vertical column or removes the gap between the main alpha keys and the numpad. This results in a board that is significantly narrower than a traditional office keyboard but maintains the essential 99 keys. It is a sturdy piece of hardware, weighing enough to stay planted on a desk during heavy typing sessions.
The chassis is constructed from high-quality plastic that feels dense rather than hollow. This is a crucial distinction, as many budget mechanical keyboards suffer from a "pingy" sound caused by empty space inside the case. Epomaker has addressed this by implementing a gasket-mount structure. In this design, the internal plate is not screwed directly into the case. Instead, it is cushioned by gaskets, allowing for a slight amount of flex. This flex absorbs the impact of your keystrokes, leading to a softer bottom-out feel and a more consistent acoustic profile.
The keycaps are another high point. They are made of dye-sublimated PBT in a Cherry profile. PBT is widely preferred over ABS plastic because it does not develop a greasy shine after weeks of use. The legends are crisp and clean, ensuring that the letters will not fade even after millions of actuations. The Cherry profile offers a comfortable, familiar height that most typists find natural, making the transition from a standard keyboard almost instantaneous.
The smart display and control knob
A standout feature of the Pro model is the integrated 1.06-inch smart display and the adjacent control knob. Located in the top right corner, this screen provides real-time feedback on the keyboard’s status. You can check your connection mode, battery percentage, and even the current time without having to open software on your computer. It adds a layer of modern utility that makes the board feel like a centerpiece of a workstation.
The rotary knob is tactile and provides satisfying clicks as you turn it. By default, it manages volume and play/pause functions, but its true value lies in the quick navigation it offers through the keyboard's internal menu. Instead of memorizing complex key combinations to change the RGB lighting or switch between Bluetooth devices, you can simply use the knob and screen interface. This makes the keyboard much more accessible to those who are not mechanical keyboard enthusiasts.
Connectivity and battery life
Modern workflows often involve multiple devices, and the TH99 Pro is built to handle that reality. It features tri-mode connectivity, allowing users to switch between Bluetooth 5.0, 2.4GHz wireless, and a traditional USB-C wired connection. The 2.4GHz mode is particularly important for gamers, as it provides a low-latency connection that is nearly indistinguishable from a wire. Bluetooth, on the other hand, is perfect for connecting to a laptop or tablet while traveling.
The battery life is perhaps the most impressive technical specification. While many wireless mechanical keyboards struggle to include a 4,000 mAh battery, Epomaker has packed a massive 10,000 mAh cell into the TH99 Pro. This is a significant advantage for anyone who hates the "low battery" anxiety associated with wireless peripherals. Even with the RGB lighting turned on, the keyboard can last for weeks on a single charge. If you turn the lighting off and rely on the high-efficiency sleep modes, you could potentially go months between charges. This makes it one of the most reliable wireless options currently available in this price range.
Performance and acoustics
The typing experience on the TH99 Pro is defined by its internal dampening. Epomaker has used five layers of sound-dampening materials, including poron foam and silicone pads. These layers fill the internal voids and surround the switches, cutting out unwanted noise. The result is a "thocky" sound profile—a deep, muted thud that is highly sought after by keyboard hobbyists. It sounds professional and refined, making it suitable for an open office environment where a loud, clicky keyboard might be a distraction.
The switches are hot-swappable, meaning the PCB has sockets that allow you to pull out a switch and push in a new one without using a soldering iron. This provides a great deal of future-proofing. If a single key starts to fail, or if you simply decide you want to try a more tactile or clicky switch later on, you can do so in minutes. The board supports both 3-pin and 5-pin switches, giving you access to nearly every mechanical switch on the market.
Software and customization
For those who want to dig deeper, the companion software allows for extensive customization. You can remap every key on the board, which is useful for programmers or creatives who use specific macros in their workflow. The RGB lighting is also fully programmable, with various patterns and colors available to match your desk aesthetic. While the hardware is great out of the box, the software ensures that power users can tailor the board to their specific needs.
The software is functional and straightforward. It handles the basics well, such as setting up macros or updating the firmware. While it may not have the flashy visual polish of some major gaming brands, it gets the job done without being overly bloated or demanding on system resources.
Final thoughts
The EPOMAKER TH99 Pro is a well-balanced peripheral. It takes the best parts of enthusiast keyboard culture—like gasket mounting, heavy sound dampening, and hot-swappable parts—and puts them into a package that is practical for everyday use. The addition of the large battery and the smart screen makes it feel like a premium upgrade over standard mechanical boards.
It is a tool designed for someone who spends a significant portion of their day typing. The 1800 layout is a masterclass in space management, providing all the utility of a numpad without the unnecessary width. For less than ninety dollars, it offers a level of build quality and a feature set that makes it a very compelling choice for professionals and enthusiasts alike.
