A flatter shape and replaceable AA, or a rechargeable mouse with more scroll controls? Check the package and your actual grip.

The flatter form and replaceable AA power suit a bag-first shortlist when you do not need the MX model’s scroll-wheel options.
Skip it if: You prefer a taller shape or want rechargeable power and the MX scroll controls.
Find on Amazon Check manufacturer details ↗Its wheel mode and rechargeable design give you concrete features to compare. Choose them because they match your work, not because a larger DPI number proves comfort.
Skip it if: You want the flattest option here, prefer an AA battery, or will not use the extra controls.
Find on Amazon Check manufacturer details ↗A compact mouse is a fit decision before it is a specification contest. Pebble Mouse 2 M350s is the flatter option here; MX Anywhere 3S has a taller profile and a different control set. Your hand, grip and movement space can matter more than a headline sensor number. This guide does not claim that either shape is comfortable for every person.
For a straightforward portable setup, begin with Pebble and ask what feature would make you switch. For work where the MX wheel modes or rechargeable power are useful, compare the MX deliberately. We have not performed tracking, battery-life or comfort tests.
Logitech’s support tables label the axes differently for these two products. The table below restates the physical measurements as length, width and thickness so the long body dimension is not mistaken for how tall the mouse sits.
| Check | Pebble Mouse 2 M350s | MX Anywhere 3S |
|---|---|---|
| Length × width | 106.7 × 58.7 mm | 100.5 × 65 mm |
| Thickness / vertical profile | 26.62 mm | 34.4 mm |
| Power routine | Replaceable AA | Rechargeable; USB-C charging |
| Receiver assumption | Bolt compatible; receiver not included | Regular consumer package: Bolt receiver not included |
| Decision to investigate | Slim form and simple portable kit | Wheel controls and rechargeable power |
The listed vertical-profile difference is 7.78 mm. That calculation can help when checking a shallow pouch, but it does not measure grip quality. Draw the two body outlines on paper or compare the forms in person when possible. Leave space around the outline for movement; the mouse body is not the entire mousing area.
Neither a shorter body nor a narrower body automatically gives more useful room beside the keyboard. Where you place the keyboard, your working movement range and the objects on the surface determine that. Reposition existing equipment first if the actual problem is a crowded layout.
Bluetooth can keep a USB port free on a supported computer. If your work computer requires a receiver, the regular consumer product’s compatibility statement is not a promise that the box includes one. Confirm the exact package and receiver family before adding anything to the cart.
The word wireless is also not evidence of operating-system support for every optional feature. Check the relevant system requirements and any software restrictions on a managed computer. Do not buy a package on the assumption that charging by USB turns the mouse into a wired data device.
A replaceable battery and rechargeable power create different small chores. Think about where a spare AA would live, or where the charging cable would reach, using your normal routine rather than a theoretical maximum runtime. Manufacturer battery estimates are not results from our own use.
Finally, check model names carefully: Pebble M350 and Pebble Mouse 2 M350s are different labels, as are MX Anywhere generations and business packages. Pick the exact product that satisfies the shape, feature and connection checks. The Amazon links open searches for those model names, so confirm the actual listing before ordering.
