No matter how many times I tried switching to a keyboard that was even slightly taller than a low-profile model, typing consistently became uncomfortable for me. For that reason, I turned my attention to the A4Tech FX53 and A4Tech FX55. Both are equipped with Fstyler scissor-switch mechanisms. From a practical standpoint, this choice of switch type is a key characteristic and a relevant factor for users who prioritize low key travel and a flat typing profile.

Positioning and price
Their pricing is also relatively modest: approximately $25 for the FX53 and $30 for the FX55. That places both models at or below the $30 mark. This is notable, as keyboards in this price range are less common subjects for detailed reviews, particularly when they target specific ergonomic or design preferences.
Advantages
Notably, the low price does not translate into an overly minimal feature set. For example, it is uncommon to see a USB Type-C port on keyboards in this price segment, especially with a detachable cable included as a separate accessory rather than permanently fixed.
As a result, the FX53 or FX55 can be connected directly to a smartphone without adapters, using a standard USB-C cable.
Next are the Fstyler scissor switches with a 2 mm key travel. They are noticeably stiffer than the membrane switches used in the KV-300H, resulting in higher actuation resistance during typing.
The keyboards also include adjustable feet that provide a typing angle of either 5 or 8 degrees. In addition, an Fn key is present, extending the functionality of the F1 through F12 keys.
Differences
From this point on, the distinctions become more apparent. The most obvious difference is size and layout. The A4Tech FX53 uses a relatively uncommon 75% layout: it omits the numeric keypad but avoids more aggressive layout compromises. It retains full-size arrow keys and a dedicated function row, all within dimensions of 133 × 315 × 18 mm and a weight of 751 g.
The A4Tech FX55, by contrast, is full-size in terms of physical dimensions – 133 × 437 × 18 mm – with the same stated weight of 751 g, but not strictly in terms of a conventional key count. It includes more keys than might be expected at first glance.
Additional keys provide shortcuts for device locking, minimizing windows, opening the emoji panel, and quick access to screenshots. There are also dedicated keys for Microsoft 365 Copilot and Copilot.
I cannot speak for other users, but I personally make a deliberate effort to avoid using any AI assistants. In this context, the placement of the Copilot-related keys directly above the Backspace key proves problematic. During typing, this layout results in unintentionally triggering the Windows assistant more often than intended, which can be distracting and counterproductive in everyday use.
Switches
Regarding typing experience, the scissor switches here are not typical laptop-style switches. They feel somewhere between linear mechanical switches and low-profile membrane switches, offering a balance of tactile feedback and relatively short travel.
They sit right in the middle – both in terms of keycap height, key travel depth, and actuation force – striking a balance between the lightness of low-profile membranes and the more substantial feel of mechanical switches.
These switches do require a short adjustment period, but overall they leave very few complaints. Personally, I returned to my usual typing speed within about a week.
Drawbacks
Now for the main drawback of both the A4Tech FX53 and FX55: neither keyboard has backlighting. For users who cannot touch-type, this can create significant adaptation challenges, especially in low-light environments.
Another downside is the use of ABS plastic, which is extremely soft. In fact, after just a month of use, I had already polished part of the Spacebar that I press with my thumb constantly – whereas on other keyboards, this level of wear typically takes years to appear.
This doesn’t affect functionality. In fact, the keycaps aren’t painted – they use laser engraving – so while they’re durable, don’t be surprised if repeated use eventually wears them to a polished shine.
Summary
If touch-typing isn’t an issue for you, the A4Tech FX53 and FX55 are very compelling options. They are affordable, more versatile than I initially expected, and while they do have drawbacks, these are forgivable. The combination of features and functionality at this price point is rare, making both models a strong recommendation.
