The Logitech B100 is our overall recommendation for regular office and desktop use. Its larger ambidextrous body, simple controls and plug-and-play connection make it suitable for everyday work.
Choose the Logitech M90 if you prefer a slightly smaller mouse with 1000 DPI tracking. The A4TECH OP-720 is better for users who want a larger ergonomic shape, while the Rapoo N100 offers the lowest-priced practical option among these models.
All four are wired optical mice, so you do not need to manage batteries, charging or a wireless receiver.
A wired mouse connects directly through a USB port. It does not require a battery, charging cable or separate wireless dongle. This reduces the number of parts that may become lost or cause connection problems.
Wired models are especially practical for:
The cable limits movement compared with a wireless mouse, but this is rarely a major issue when the mouse stays on the same desk.
The Logitech B100 Optical USB Mouse is a straightforward option for office, study and everyday desktop use. It has an ambidextrous full-size design that can be used with either hand.
Its 800 DPI optical sensor is suitable for documents, spreadsheets, browsing and other regular tasks. The three-button layout keeps operation simple, while the 1.8-metre cable provides enough reach for most desktop setups. It also works through a plug-and-play USB connection without requiring additional software.
Ryans currently lists the Logitech B100 at Tk 449, with eCommerce-ready stock. Price and availability may change.
Choose the B100 if you want a larger, simple mouse for regular office work and do not require high DPI, additional buttons or gaming features.
The Logitech M90 USB Mouse is another dependable wired option. Ryans classifies it as a regular small mouse, making it more suitable for users who find the B100 too large.
It has a 1000 DPI optical sensor, three buttons and an ambidextrous design. The USB plug-and-play connection allows it to work without installing additional software.
The M90 and B100 currently have the same listed price. Therefore, the better choice mainly depends on size and hand comfort rather than cost.

Choose the M90 if you prefer a smaller body and slightly higher cursor sensitivity than the B100.
The A4TECH OP-720 Optical USB Mouse is a useful option for buyers who prefer a larger ergonomic shape.
It offers 1200 DPI optical tracking, three buttons and a plug-and-play USB connection. A4TECH states that the model has a dust-resistant wheel and buttons rated for up to five million clicks. These features make it relevant for regular scrolling and repeated office use.
However, the manufacturer’s click rating should not be treated as a guarantee that every unit will last for a fixed number of years. Actual lifespan depends on usage, handling and working conditions.
Ryans currently lists the A4TECH OP-720 at Tk 425, with eCommerce-ready stock. Price and availability may change.
Choose the OP-720 if you want a larger ergonomic mouse with 1200 DPI tracking and a dust-resistant scroll wheel.
The Rapoo N100 USB Optical Mouse is the most affordable option in this list. It provides a wired USB connection, an ergonomic design and a 1600 DPI optical sensor.
The higher DPI allows the cursor to move farther with less hand movement. However, DPI alone does not determine overall quality. Shape, sensor consistency, button feel and warranty support are also important.
Ryans currently lists the Rapoo N100 at Tk 350, with an Add to Cart option. Price and availability may change.
Choose the N100 if your budget is limited and you need a basic branded mouse for home, study or office work.

A mouse that feels too small or too large can become uncomfortable during long work sessions. If possible, compare the B100, M90 and OP-720 in hand before choosing.
Check that the left and right buttons register each click correctly. The scroll wheel should move smoothly without skipping or scrolling in the wrong direction.
The cable should be long enough to reach your computer without being stretched. Avoid placing sharp bends near the USB connector or mouse body.
Optical mice generally work well on a plain mouse pad or non-reflective desk. Glass, glossy or uneven surfaces may affect tracking.
Buy a new product with an invoice and valid warranty. This makes it easier to request support if the buttons, wheel, sensor or cable develops a problem.
The Logitech B100 is the best overall choice for users who want a larger and straightforward office mouse. The Logitech M90 is a better alternative for smaller hands, while the A4TECH OP-720 provides a larger ergonomic design and useful durability-focused features. The Rapoo N100 is the most practical option for buyers who want the lowest price.
