This article takes a close look at the LETTON Wireless Keyboard Mouse Combo — Portable Full-Size Retro Typewriter Style Set (Black/Red). Beyond the spec sheet, it covers which devices the set works with and the pitfalls people tend to notice only after buying.
Overview
The short version: the LETTON Wireless Keyboard Mouse Combo (Black/Red) is for people who want their desk to look fun first. It pairs a full-size keyboard styled like a retro typewriter with a silent mouse.
It is good enough for documents, schoolwork and everyday office tasks. It is not a good fit for gaming, for anyone who needs a Japanese JIS layout, or for anyone who wants rechargeable devices.
The keyboard has 104 round keycaps, 13 of which are multimedia hotkeys. The mouse switches between three DPI levels (800/1200/1600) and has silent clicks.
Both connect over 2.4GHz wireless through a single USB nano receiver, with a stated range of up to about 10 meters.

That rating is high, but the sample is small, so treat it as a rough signal. A few new reviews could move the average noticeably.
Key Features
and What They Mean in Use
Round keycaps: the look and the feel The round, typewriter-style keycaps are the main reason to buy this set. On a desk it looks nothing like an ordinary square-key keyboard.
Round caps can feel like a smaller target than square ones, though, so expect a few missed keystrokes and slower typing for the first few days.
Floating design The keycaps sit above the base, so dust and crumbs are easier to see. They are also easier to clear out.
A quick pass with compressed air or a soft brush keeps it tidy.
Switch type is not stated The listing does not say whether the keyboard uses membrane or mechanical switches. 'Typewriter style' describes the look, and the typing feel may not match a real typewriter or a clicky mechanical keyboard.
If a loud, clacky feel is what you want, you may be disappointed.
Silent mouse The mouse has silent clicks, which helps in libraries, shared offices or late at night. Three DPI steps up to 1600 are plenty for office work and browsing.
On a high-resolution monitor, you will probably leave it at 1600.
Compatibility Guide
The official compatibility list reads: Windows 2000/ME/XP/7/8/10, Vista, Chromebook and smart TVs. It is plug-and-play with no driver needed.
Plug the receiver into a USB 2.0 port and it works.
| Device | Listed? | Notes |
|---|---|---|
| Windows PC / laptop | Yes (up to Windows 10) | Windows 11 is not named |
| Chromebook | Yes | USB-C-only models need an adapter |
| Smart TV | Yes | Only TVs that accept USB keyboards and mice |
| Mac | No | Not on the official list; treat any use as unsupported |
| iPad / smartphone | No | USB-A receiver needs an adapter; unsupported |
The OS list mostly names older versions of Windows, and Windows 11 is not mentioned. Standard USB keyboards and mice usually work with the drivers built into the OS, but the manufacturer has not said this model supports Windows 11.
If that worries you, check the latest listing details or the Q&A section on the product page.
The receiver uses a USB-A plug. Many thin laptops and Chromebooks now have only USB-C ports, so you would need a USB-C to USB-A adapter or hub.
Because one receiver handles both devices, the set takes up only one port.
The stated range is up to about 10 meters. The 2.4GHz band is shared with Wi-Fi routers and microwave ovens, though, so input can drop in crowded wireless environments.
If the receiver is in a port on the back of a desktop PC and response is spotty, moving it closer with a USB extension cable usually helps.

Prices change often with sales and stock levels, so check the product page for the current price before buying. The seller and shipper is Tokyo Prime (東京プライム), which also handles warranty support.
The product is listed as released in 2024 or later and is still on sale.
The box contains only the receiver and the manual, with no batteries. If you want to start using it the day it arrives, have two AAA batteries and one AA battery ready.
Living With Battery Power
The keyboard runs on two AAA batteries and the mouse on one AA battery. There is no USB charging.
The listing gives no battery-life figures, so we will not guess at them. The 30-minute auto sleep keeps drain down while the set is idle.
The upside of disposable batteries is that a dead set comes back the moment you swap them, and there is no built-in battery to wear out and take the device with it. The downside is the ongoing hassle and cost.
Rechargeable NiMH cells are a simple way around that.
How to Compare Similar Sets
Several brands sell wireless sets with round, typewriter-style keys, often in many colors.
- Layout: is it 104-key, or a Japanese layout?
- Power: disposable batteries or rechargeable?
- Receiver plug: USB-A or USB-C?
- Connection: does it also support Bluetooth?
This LETTON set is the basic version: 2.4GHz only, battery-powered, with a USB-A receiver.
You buy it for the black/red color scheme and the retro look rather than a long feature list. If rechargeable power or Bluetooth matters to you, compare other models.
If you need fast response and extra buttons for gaming, start with a gaming-focused set instead.
Who It's For
- Fans of retro typewriter styling: it suits anyone who wants a distinctive desk or enjoys the act of typing. The black/red finish works as an accent even in a plain room.
- People who need quiet: the silent-click mouse is easy to use in libraries, shared offices or late at night without bothering anyone.
- Laptop users working on an external monitor: one receiver runs both devices, which helps on laptops with few USB ports. The full-size layout includes a number pad, which is handy for spreadsheets and budgeting.
- Gift shoppers: the look is clearly cute, so it is an easy pick for students or family members who have started working from home.
Before You Buy
Check the layout 104 keys is the usual count for a full-size US English layout. Full-size Japanese JIS keyboards usually have 108 to 109 keys.
The listing does not say which layout this one uses. If it is US, symbols are in different places and there is no Hankaku/Zenkaku key, so switching Japanese input works differently.
Check the key legends in the product photos before ordering.
'Portable' but full-size The product name says 'portable' and 'travel', but this is a full 104-key board with a number pad. No weight is listed.
If you plan to carry it every day, a compact or folding keyboard is more practical.
Not meant for gaming The mouse tops out at 1600 DPI, and this is a 2.4GHz office set.
Nothing in the listing covers response time or how many keys register at once. For serious competitive gaming, choose dedicated gaming gear.
Mac, USB-C and Windows 11 are at your own risk
As the compatibility guide shows, Mac, phones and tablets are not on the official list, and Windows 11 is not named. USB-C-only devices also need an adapter.
Few reviews so far
That is too few to judge durability or unit-to-unit variation, so read the newest reviews too.
Listing names vary
The product name says 'Leton' while the manufacturer field says 'LETTON'. Many sets in this category look alike, so before ordering, check that the photos, color and ASIN (B0FHGFZZ2Q) match the product you want.
FAQ
Q. Do I need to install drivers?
A. No. Plug in the USB nano receiver and it works.
Q. Are batteries included?
A. No. You need two AAA batteries for the keyboard and one AA battery for the mouse.
Q. Can the keyboard and mouse be used separately? A.
The listing says one receiver runs both at the same time and that they can also be used separately. Since there is only one receiver, though, the set is not suited to splitting between two computers at once.
Q. Does it work with a Mac? A.
Mac is not on the official OS list. It may be recognized as a standard USB input device, but key mapping and behavior are not guaranteed.
Q. Do I need to switch it off when I'm not using it? A.
It goes to sleep automatically after 30 minutes without input. If you won't use it for several days, take the batteries out to avoid drain and leaks.
