Logitech's wireless lineup runs from the MX Master 4 down to the M185, M310 and M510 that still anchor the budget tier — and our office mouse round-up covers the premium side of that range. But treat these three as the same mouse in three sizes and you'll miss what actually matters: different control layouts, different receiver compatibility, and different lifecycle status.
The M185 and M310 remain active products on Logitech's US store. The M510 has been moved to Logitech's end-of-life catalog, even though Amazon stock continues to circulate. All three belong to the same USB-receiver generation: 2.4 GHz wireless, AA battery power, and no Bluetooth on any of them.
This guide walks through each model using current official Logitech specifications, then corrects the two revision traps that trip up buyers: the M510's sensor history and the M185's receiver compatibility. You'll also find a clear replacement path for M510 owners who want the same controls rather than just "another wireless mouse."
It's written for anyone choosing among budget Logitech mice, replacing a lost or dead receiver, or deciding whether a discontinued M510 is still worth buying.
Logitech's Philosophy — The USB-Receiver Era That Still Ships
Logitech's entry wireless mice are built around a simple promise: a plug-in 2.4 GHz USB receiver, a single AA battery, and an optical sensor that resolves at 1000 DPI. None of the three featured models supports Bluetooth or multi-device Easy-Switch. If you want pairing to multiple machines with a button, these are not the family to buy.
That limitation is also the source of their reliability. A dedicated 2.4 GHz receiver means no Bluetooth stack to negotiate, no pairing dropouts tied to OS updates, and a 10 m wireless range from a tiny USB dongle. The trade-off is a receiver you can lose — and, on some hardware revisions, replace incorrectly.
The three models separate cleanly by size and controls. The M185 is the compact travel mouse. The M310 adds a larger ambidextrous shell without adding buttons. The M510 adds the full sculpted body, two thumb buttons, and a tilt wheel. Once you know which trait you actually want, the decision is mostly made.
Entry Tier — Logitech M185 Wireless Mouse
The M185 is the smallest and lightest of the three, and the most straightforward. Logitech still sells it as an active product, which matters when you're comparing it to a discontinued model.

compact budget tier. Check Price on Amazon
Pros
- Light and small enough for a laptop bag
- Simple three-button layout that requires no setup
- Still actively sold by Logitech, so replacement stock is normal retail
- Long battery runtime from a single AA
Cons
- No thumb buttons for back/forward navigation
- No Bluetooth or multi-device support
- Receiver compatibility varies by hardware revision
Verdict: a dependable portable mouse if the compact shell fits your hand. It is not a productivity tool for people who live on browser shortcuts.
Perfect for: travelers, students, and anyone using a mouse as a secondary input device.
Receiver replacement trap: not every M185 is Unifying-compatible
The M185 is Logitech's best example of why you should check the underside of the mouse, not the family name. Logitech's own revision documentation shows multiple internal hardware versions. Some, like the M-R0038 revision, are documented with a C-U0007 receiver using the Logitech Unifying protocol. Others, like M-R0061, pair a C-U0010 receiver over non-Unifying 2.4 GHz.
This matters when a receiver gets lost or stops pairing. A replacement Unifying receiver will not necessarily pair with every M185. Before you buy a receiver, read the underside model number and any receiver markings. Match the replacement to that specific revision rather than assuming every M185 works with Unifying. If you need a compact mouse without this ambiguity, the small-hand options in our small mouse guide cover newer models.
Mid-Size Tier — Logitech M310 Wireless Mouse
The M310 moves up in size but not in features. It is functionally closer to the M185 than to the M510: three buttons, vertical scrolling only, and no thumb controls. The reason to buy it is the larger ambidextrous shell.

| Range | Up to 10 m |
| Status | Active on Logitech US store; Amazon stock intermittent |
| OS support | Windows, macOS, ChromeOS, Linux |
budget full-size tier. Check Price on Amazon
Pros
- Comfortable larger shell for either hand
- Battery indicator and on/off switch help extend runtime
- Quoted battery life longer than the M185
- Simple enough for shared or office use
Cons
- No thumb buttons, so back/forward requires keyboard shortcuts or on-screen controls
- No horizontal scroll
- Amazon availability has been intermittent even though Logitech lists it as active
Verdict: a solid choice if you want M185 simplicity in a larger body, but it doesn't add any productivity controls to justify an upgrade from the M185.
Perfect for: office workers who want a full-size ambidextrous mouse without extra buttons.
The M310's internal model number is M-R0014, and its bundled receiver is a 18.7 × 14.4 × 6.1 mm nano receiver weighing 1.8 g. That detail only matters if you need to identify a replacement. The bigger practical point is the recurring upgrade gap: many M310 owners later ask for "an M310-sized mouse with side buttons," and that request takes them out of this family into the Signature M650 or M720 lines. Our office mouse round-up covers those current options in detail.
Discontinued Tier — Logitech M510 Wireless Mouse
The M510 is the only one of the three with real navigation controls, and the only one Logitech no longer manufactures. It remains widely available through Amazon, which is why it still appears in shopper guides years after Logitech moved it to the end-of-life catalog.

mid-range legacy tier. Check Price on Amazon
Pros
- Only model here with two thumb buttons and horizontal tilt scrolling
- Full-size sculpted body suits larger hands better than the other two
- Unifying-ready receiver lets one dongle pair with other compatible Logitech devices
- Long quoted battery life from two AA cells
Cons
- Discontinued by Logitech, so warranty and support are in legacy territory
- Heaviest and bulkiest of the three
- Sensor history creates confusion: not every M510 ever sold uses the same sensor
- Not Bluetooth or multi-device
Verdict: still the right buy if you specifically need the M510's control layout, but only if you accept that you're buying into an end-of-life product.
Perfect for: larger-handed users who rely on back/forward thumb buttons and horizontal scrolling in office or music-production workflows.
Sensor history: the laser-to-optical correction
Many older M510 listings and reviews call it a laser mouse. That was true for early hardware revisions. RTINGS specifically documents that its original review sample used a laser sensor, while newer M510 units use optical tracking with a maximum around 1000 CPI. Logitech's current EOL specification lists High Precision Optical Tracking at 1000 DPI ±.
This matters because an old specification sheet is not evidence about the unit in the box you buy today. If you're comparing an M510 against a current mouse, don't quote the laser sensor as a current advantage. It isn't one.
Part number drift
Logitech's EOL page identifies the M510 with part number 910-001822, but current Amazon inventory for the relevant ASIN associates 910-006030. This is consistent with later packaging and hardware revision differences, not a counterfeit signal. If you're hunting for a specific revision, check the product label rather than trusting a marketplace part number alone.
Logitech Legacy vs Current Lineup — The Honest Comparison
The three legacy models are not Logitech's entire modern range. The current consumer productivity catalog still includes entry USB-receiver models like the M170 and M330 Silent Plus; compact Bluetooth models like the M240 Silent and Pebble Mouse 2 M350s; mainstream Signature M550 and M650; and full-size multi-device models like the Marathon M705 and M720 Triathlon.
For M510 owners, the closest current replacements by control set are the M705 and M720. Both offer extra navigation controls and multi-device connectivity, though neither is a one-for-one twin of the M510. The Signature M650 is often suggested as a modern successor, but its hand feel and control layout differ enough that a long-time M510 user may still prefer an existing unit or an M720.
The practical decision tree sits in the table below.
| Need | M185 | M310 | M510 |
|---|---|---|---|
| Smallest, lightest, portable | Yes | No | No |
| Larger ambidextrous shell | No | Yes | No |
| Full sculpted shape for larger hands | No | No | Yes |
| Thumb buttons | No | No | Yes |
| Horizontal tilt scrolling | No | No | Yes |
| Bluetooth | No | No | No |
| Multi-device | No | No | No |
| Still manufactured by Logitech | Yes | Yes | No |
If your real requirement is Bluetooth or multi-device behavior, skip all three and look at the current Signature or Pebble lines. If you need a compact low-cost mouse and nothing else, the M185 is still perfectly serviceable.
Which Logitech Wireless Mouse Should You Buy?
Buy the M185 if you want the smallest, lightest option and don't need navigation buttons. It works for travel, secondary PCs, and shared family computers. Just verify the receiver revision if you ever need a replacement.
Buy the M310 if you want the same simple controls in a larger shell for either hand. It's the middle option for people who find the M185 too small but don't want thumb buttons.
Buy the M510 only if you specifically need the thumb controls and horizontal scrolling, and you're comfortable with a discontinued product. The control layout is still the main reason people seek out this exact model.
Look at the current range instead if you need Bluetooth, multi-device pairing, or simply want a product Logitech still supports as a mainline item. The M650 and M720 are the most relevant paths for M510-style productivity, while the Pebble 2 and M240 cover compact portability. For small-hand users, our dedicated guide breaks down newer compact options.
Frequently Asked Questions
Q: Is the Logitech M510 discontinued?
Yes. Logitech now places the M510 in its end-of-life catalog and no longer manufactures it. Amazon and other sellers may continue to sell remaining stock, so it can still be bought, but it is not part of Logitech's active consumer range.
Q: Does the M510 use a laser or optical sensor?
Current M510 units use High Precision Optical Tracking at 1000 DPI ±. Early hardware revisions used a laser sensor, which is why some older reviews still describe it as laser. Check the specific unit's revision rather than assuming every M510 is optical.
Q: Are all Logitech M185 mice Unifying-compatible?
No. Logitech's own revision documentation shows both Unifying and non-Unifying M185 versions. Some revisions, like M-R0038, use a Unifying receiver, while others, like M-R0061, use a factory-paired non-Unifying receiver. Check the underside model number before replacing a receiver.
Q: Which current Logitech mouse most closely replaces the M510?
There is no exact one-for-one replacement. The closest current models for extra navigation controls are the Marathon M705 and M720 Triathlon. Both add multi-device support, but their hand feel and scroll wheels differ from the M510.
Q: Do the M185, M310 and M510 support Bluetooth?
No. All three rely on a 2.4 GHz USB receiver. If you need Bluetooth, look at current Logitech models like the M240 Silent, Pebble Mouse 2 M350s, or the Signature M650.
Q: Are the quoted battery lives realistic?
The figures are "up to" estimates under ideal conditions: 12 months for the M185, 18 months for the M310, and 24 months for the M510. Actual runtime depends on battery quality, workload, RF conditions, and how often the mouse is left on. Treat them as ceilings, not guarantees.
Q: Does the M510 work with Windows 11?
Yes. Logitech lists Windows 10/11 or later, macOS, ChromeOS, and Linux kernel 2.6+ for the M510. The same broad compatibility applies to the M185 and M310 through their USB receivers.
Q: Can I use an M185 receiver with another Logitech keyboard or mouse?
Only if your specific M185 receiver is Unifying-compatible. Non-Unifying M185 revisions use a factory-paired receiver that will not pair with other Logitech devices. The receiver markings and the M185's underside model number are the only reliable indicators.
Conclusion
The M185, M310 and M510 are not three sizes of the same product. They are three answers to three different needs: portable simplicity, larger ambidextrous comfort, and full controls on a discontinued shell. The M185 remains the best low-cost portable pick among the three, the M310 fills the larger simple-shape gap, and the M510 survives only because its thumb buttons and tilt wheel still matter to a specific group of users.
If you're replacing an M510, be honest about which trait you're trying to preserve. If it's the compact size, the M185 is a downgrade in controls. If it's the controls, the M705 and M720 are the current paths worth comparing. If it's simply "a reliable wireless mouse," any of the three works, but the M185 and M310 enjoy the advantage of still being active Logitech products.
