TV keyboard discounted to three hundred crowns: Eternico KSB5250 has a touchpad and CZ/SK keys

Typing text on a smart TV one letter at a time using a remote control is a pain. One customer summarized it perfectly: “I don’t understand how I lived without it.” The Eternico KSB5250 for 329 CZK is a compact wireless keyboard with a touchpad and Czech layout that solves this – you connect it to a TV, tablet, or computer, you have both a keyboard and a mouse in one, and you don’t have to get up from the couch. For 329 CZK, it’s a great purchase that will genuinely change your comfort when using the TV.

Quick summary:
✅ Makes sense if you control a smart TV, HTPC, projector, or tablet and want a keyboard with a touchpad in CZ/SK layout for a minimal price – for 329 CZK, you won’t buy anything better with a touchpad.
⚠️ Consider if you plan to use it as your main computer keyboard – a small Enter key, narrow arrow keys, and a touchpad that doesn’t match the quality of a laptop trackpad are not sufficient for all-day work. Some Samsung TVs have compatibility issues.
💡 For 329 CZK, you get a CZ/SK scissor-switch keyboard with a touchpad, Bluetooth 5.1 + USB dongle, a rechargeable battery via USB-C, and connectivity to 3 devices simultaneously.

What it’s good for and why the touchpad is crucial

Main use case: controlling the TV from the couch. The keyboard replaces the annoying text input using arrows on the remote control, and the touchpad functions as a mouse – you navigate menus, launch applications, search for movies. Customers use it with Google TV streamers, Android TV boxes, HTPCs, projectors, and tablets. One reviewer describes buying it for watching series via a projector from bed – “unbeatable for the price.”

Key detail: a touchpad that actually works. With cheap keyboards with touchpads, it’s often a disaster – false clicks, erratic movements. A customer who had previously tried three competing models writes: “Here, the touchpad finally works as it should.” Another reviewer (from Rosice u Brna) found Bluetooth pairing took just a few seconds.

Connectivity and practical details

Eternico KSB5250 connects in two ways: a 2.4GHz USB dongle (for TVs and devices without Bluetooth) and Bluetooth 5.1 (two profiles for laptop, tablet, phone). A total of 3 devices simultaneously with switching via Fn+1/2/3. The dongle stores in a compartment within the keyboard to prevent loss. A range of 8–10 meters covers a typical living room.

Rechargeable 300mAh battery via USB-C – no need to replace AA/AAA batteries. Customers report they haven’t managed to drain the battery yet, but realistically, expect to recharge it once every few weeks with occasional use. After 20 minutes of inactivity, the keyboard automatically goes to sleep. Dimensions 37.7 × 12.5 × 2.2 cm and weight 500 g – fits into a backpack or a TV drawer. Scissor-switch keys with CZ/SK localization and labels for both Windows and macOS. 12 multimedia keys via Fn (volume, playback, browser).

What to watch out for

Compatibility with Samsung TVs is problematic. One customer reports that Bluetooth pairing with their Samsung TV didn’t work at all; another (Samsung Series 5) connected via dongle, but the keyboard only worked in some applications – not in YouTube or Skylink. No problems have been reported with Google TV streamers, Android TV boxes, or LG TVs. If you have a Samsung TV, verify compatibility before purchasing.

Build quality matches the price – the plastic body flexes slightly under pressure, and there’s a sharper edge between the top and bottom parts. The touchpad is functional, but a reviewer from Kladno points out that “the surface is rougher, mouse movement is sometimes jerky, and gestures don’t always work” – it doesn’t function as a replacement for a laptop trackpad, but it’s sufficient for occasional TV control. The small single-row Enter key and narrow arrow keys are a compromise of the 65% format. Switching channels with Fn+1/2/3 is “awkward” – the USB dongle is in position 3, but appears as the first on the LEDs, which is confusing. Backlighting and foldable feet are missing.

Verdict

The Eternico KSB5250 for 329 CZK is the cheapest way to make controlling your smart TV, HTPC, or tablet more pleasant. CZ/SK layout, functional touchpad, Bluetooth + dongle, rechargeable battery via USB-C, and connectivity to three devices – you won’t find this combination anywhere else for less than three hundred crowns. It’s not a keyboard for all-day work, and the build quality matches the price, but for what it’s designed for – occasional typing and control from the couch – it works exactly as it should.
