Why this keyboard is interesting

This Eternico K800F keyboard is aimed at people who want to switch to a mechanical keyboard but don’t want to spend thousands. You get a full-size layout with 111 keys and a numeric keypad, tactile Gateron Brown switches, and full CZ/SK localization – including backlit Czech characters, which is not a given for inexpensive keyboards. According to reviews, the main surprise is the pleasant keypress and quality sound, which people compare to significantly more expensive pieces. At 1,119 CZK with code 30ETERNICO2026, it’s one of the cheapest ways to get a wireless mechanical keyboard.

Key parameters in plain language

The core consists of tactile Gateron Brown switches, which have a gentle tactile feedback without a loud click – suitable for long typing sessions and gaming without disturbing others. You can connect it in three ways: via a 2.4GHz USB receiver, Bluetooth 5.0 (two channels), or a USB-C cable, to a total of up to four devices. It also features RGB backlighting with 22 effects, full n-key rollover and anti-ghosting for flawless keypress registration, and switching between Windows and macOS. Power is provided by a built-in 3,750 mAh battery charged via USB-C.

Practical aspects: switching, battery life, charging

Here, two things need to be addressed honestly. Firstly, although the keyboard can handle up to four devices, switching between them is done with a three-position slider, not a key – according to reviews, those who frequently switch between computers will find this inconvenient. Secondly, battery life primarily depends on the backlighting: with RGB enabled, expect battery life in the order of days; with it off, easily a week or more. It charges via the included braided USB-C cable (1.5 m), but beware – the manufacturer explicitly warns that it must not be charged with a fast charger (QC/FC).

A practical plus is the battery status indication directly via the backlighting and the fact that the keyboard can also be used purely via cable. The construction from a combination of aluminum and ABS plastic feels above its price class, according to users, although isolated defective units have appeared. A minor disadvantage for owners of mice from the same brand: the 2.4GHz receiver cannot be shared, so you will need two.

What users say

The rating is solid: 4.6 out of 5 from 45 customers and 87% of buyers recommend the keyboard. Most often, people praise the pleasant and quiet keypress, quality sound, effective backlighting, and price/performance ratio – many reviews describe it as the best in this price category and compare it to more expensive keyboards from established brands. They also appreciate that everything is set directly from the keyboard.

However, recurring criticisms also appear. Besides the aforementioned slider switching, some people dislike the unclear top row of F1–F12 keys, which is neither indented nor spaced, making it harder to navigate by touch. Several users complain about the unluckily placed screen lock key next to the numeric “−”, which they press accidentally, and that Caps Lock and Num Lock are not distinguished by a different color. More demanding users will be disappointed by the absence of software for key mapping and macros.

When it doesn’t make sense

If you frequently switch the keyboard between multiple computers, the slider instead of a key will annoy you – opt for a model with dedicated buttons. Those who want to deeply configure keys, macros, and backlighting in software (e.g., via VIA) will hit a wall here, as there is no application. And if you need a keyboard that lasts for weeks with full RGB, be aware that here the backlighting significantly shortens battery life. Under these conditions, it makes sense to pay extra for a more feature-rich model.

Verdict: who it’s worth it for

If you want an inexpensive and pleasant entry into the world of mechanical keyboards with Czech localization and don’t mind a few compromises in control, the Eternico K800F for 1,119 CZK is a hard-to-beat offer – especially considering its 4.6 out of 5 rating and three-year warranty. For a saving of 480 CZK compared to 1,599 CZK, you get Gateron Brown switches, quality sound, and three connection methods. Just keep in mind that device switching is via a slider, RGB shortens battery life, and software is missing. For office and home typing on a budget, however, it’s one of the best choices on the market.
