The Ussixchare Blue Colorful Wireless Keyboard and Mouse Combo is a full-size 2.4GHz wireless set with round, typewriter-style keycaps and a vivid blue color scheme.
This article goes beyond the spec sheet to cover where setup actually goes wrong and who should skip this product.
Overview
This is an entry-level keyboard and mouse set whose main purpose is making your desk look good. The keyboard uses a full-size layout with a numeric keypad and 13 multimedia hotkeys.
The mouse offers three DPI steps: 800 / 1200 / 1600.
This is not a product you buy for performance. It suits people who want a colorful but practical input setup for office work or a home PC, not people chasing typing speed or response time.
On Amazon.co.jp it holds 4.3 out of 5 stars across 54 reviews (86% positive, captured 2026-05-25) — a small sample, but a stable one.
The connection is 2.4GHz RF with a stated range of about 10 m (33 ft).
Power comes from two AAA batteries for the keyboard and one AA for the mouse. These are disposable batteries, not a rechargeable pack, which is worth thinking about before you buy.
Who It Fits, At a Glance
| Use case | Fit | Why |
|---|---|---|
| Office work / data entry | Excellent | Full-size layout with numpad |
| Secondary work-from-home desk | Excellent | No drivers, one receiver |
| Media playback control | Good | 13 multimedia hotkeys |
| Casual PC gaming | Fair | 1600 DPI cap, polling rate undisclosed |
| Competitive FPS / MOBA | Poor | RF wireless plus low DPI |
| Programmable macro use | Poor | No software or macro features listed |
Only two columns come out weak: gaming and deep customization. For typing letters and numbers, the configuration holds up well for its price bracket.
A 1600 DPI ceiling is fine for 1080p desktop work, but on a 4K panel or a multi-monitor setup the pointer can feel slow — plan on raising the OS mouse speed to compensate.
Compatibility Guide
Supported operating systems are Windows, macOS, and Chrome OS. Plug the small USB receiver into a desktop or laptop and it works immediately — no driver installation.
The keyboard and mouse share a single receiver, so you only give up one USB port. On thin laptops with few ports, that single-receiver design matters more than it sounds.
The incompatible cases are equally clear. Game consoles, smartphones, and tablets are not supported.
The dedicated-receiver design means you should assume Bluetooth is not available. If you also want to type on an iPad or a phone, this set is not the right pick.
Desktop and laptop PCs are the intended form factors.
Physical fit deserves a check too. A full-size layout with a numpad is wide, and it may not fit a shallow desk or a keyboard tray.
Measure your space, or check the dimensions on the product page, before you commit. You also need clear mousing space to the right, and the numpad pushes your mouse hand further out — something you feel over a long workday.
Receiver placement is easy to overlook. Plugging the receiver into a rear port on a desktop tower puts the metal case between it and your hands, which can make the link unstable.
A front port, or a USB extension cable that moves the receiver into the open, is more reliable. The 10 m range assumes a clear line of sight and shrinks with obstacles in between.
One more thing: 2.4GHz is the same band used by Wi-Fi and wireless earbuds.
In crowded RF environments you may see occasional dropped keystrokes or lag. If that happens, move the receiver, and try a USB 2.0 port instead of USB 3.0 — USB 3.0 ports are known to emit noise in the 2.4GHz band.

The price was ¥11,260 on Amazon.co.jp as captured on 2026-05-25.
Sales and coupons move that figure, so always check the listed price at the time of purchase. Wired classics and more feature-rich wireless sets exist in the same bracket, so the real question is how much you value the design.
The box includes the keyboard, the mouse, the 2.4GHz receiver, two AAA batteries for the keyboard, one AA battery for the mouse, and a manual.
Because batteries are included, you can start using it out of the box. Treat those cells as test batteries, though — swapping in quality alkalines or rechargeables gives more consistent runtime.
Reviews stand at 4.3 out of 5 across 54 entries, or 86% positive (captured 2026-05-25).
With fewer than a hundred reviews, that average can still shift. Don't read it with the same confidence you'd give a product with thousands of ratings.
Warranty terms vary by seller, but 30 days of initial-defect coverage is typical.

Best Use Cases
The strongest fit is someone doing daily office work or data entry who also cares how their desk looks. The full-size layout keeps numeric entry fast, while the round keycaps change the whole feel of the setup.
Accounting, inventory work, spreadsheet-heavy jobs — anything where your right hand lives on the numpad — pairs well with this layout.
The second-best fit is anyone going wireless for the first time. No drivers, one receiver, standard batteries: there is almost nothing to configure incorrectly.
If you don't want to deal with pairing sequences or firmware updates, that simplicity is a genuine advantage.
It also suits people who like the retro typewriter look and will happily trade typing feel for appearance. Desks that appear on camera, or a colorful setup for a kid's PC, are practical fits.
If you care about switch types and actuation points, this price bracket will not satisfy you.
Things to Check Before Buying
Do not buy this for gaming. The mouse tops out at 1600 DPI, and neither polling rate nor sensor model is published.
In competitive FPS or MOBA play you will likely feel the gap in both response and tracking accuracy. If gaming is the point, choose a wired mouse or a gaming wireless product that states its DPI and polling rate.
The disposable batteries surprise people after purchase. There is no rechargeable pack; when the cells run down, you replace them.
Low batteries often show up first as jumping cursor movement or dropped keystrokes — symptoms that look like a hardware defect. If behavior turns flaky, swap in fresh batteries before assuming the unit is faulty, and keep spares on hand.
Round keycaps are polarizing. Typewriter-style key tops have a smaller contact surface than standard keys, so people who press with the pad of the finger may see more mistypes.
Most adapt within a few days, but "bought it for the looks, never adjusted to the feel" is a real failure mode. If typing speed is central to your job, weigh this carefully.
Confirm the keyboard layout on the product page. Sets like this often ship with a US layout, which changes symbol placement and input-method keys.
Windows settings can partly compensate, but a mismatch between the printed legend and what you actually type is a daily irritation. Zooming into the product photos to read the key legends is the most reliable check.
Factor in the small review count. Fifty-four reviews is not a large enough sample to judge unit-to-unit variance.
An 86% positive rate is respectable, but don't trust it like a product with thousands of ratings — test every key and button while you are still inside the initial-defect window.
Amazon listing metadata sometimes disagrees with the actual product. In this category, manufacturer, seller, and model-number fields have been known to carry another product's information.
When you open the listing, don't rely on those text fields alone — confirm from the images and title that you are looking at the blue typewriter-style full-size set. Color and bundle variants are often merged onto one page as well.
FAQ
Q. Can it connect over Bluetooth?
A. No. It works only with the bundled 2.4GHz receiver, so the device needs a free USB port.
Q. Does it work with an iPad or a smartphone? A.
No. Consoles, phones, and tablets are listed as unsupported.
Choose a Bluetooth product for those.
Q. If I lose the receiver, can I buy just a replacement? A.
Sets like this generally ship pre-paired, and re-pairing or buying a spare receiver is usually not an option. Losing it likely means replacing the whole set, so leave the receiver plugged in or give it a fixed storage spot when traveling.
Q. How do I change the mouse DPI? A.
It offers three steps — 800 / 1200 / 1600 — typically switched with a button behind the scroll wheel. Check the included manual for the exact operation.
Q. How long do the batteries last? A.
No official runtime is published. It varies widely with usage and battery type, so keeping spare AAA and AA cells around is the practical answer.
Q. Can I use just the keyboard or just the mouse? A.
Yes. One receiver drives both, so using only one is fine.
Remove the batteries from the unused device to avoid needless drain.
