The MX Anywhere 3 is the rare compact mouse that real desk-bound professionals downsize to, not away from. It folds the MagSpeed scroll wheel, tracking-on-glass and three-device switching into something that disappears into a laptop bag. Buying one used is one of the smarter small purchases you can make this year, because the part that wears out on a mouse is rarely the part that fails first on this one.

Why second-hand is not “second best”
A mouse is mostly a sealed optical sensor, a few switches and a battery. The MX Anywhere 3 uses a 4000 DPI darkfield sensor that tracks on glass and gloss, and that sensor does not degrade with use the way a screen or a fan does. What you are really inheriting from a previous owner is a body that has already proven it does not creak, and a MagSpeed wheel that has already been broken in.
That MagSpeed wheel is the headline feature, and it is electromagnetic rather than mechanical ratchet. It free-spins to fly through a thousand-row spreadsheet, then clicks into precise notches for line-by-line work. Because there are fewer moving parts grinding against each other than in an old-style notched wheel, a used unit feels identical to a new one. The internal rechargeable battery is the only consumable, and it charges over USB-C in minutes for hours of use, so a slightly aged cell still comfortably lasts a full work week.
Buy the version with the scroll wheel you will actually feel every day, not the box it shipped in. On this mouse, the wheel is the product.
The savings are real
Used and refurbished gear typically lands 20-60% below new. On a premium compact mouse that is a meaningful gap in real dollars, and the feature set you get for the lower price is the same one reviewers praised at full RRP: Easy-Switch across three machines, Logi Bolt or Bluetooth connectivity, Flow to glide your cursor between two computers, and per-app scrolling and button mapping through Logi Options+. None of that is locked behind a serial number or a subscription, so a second-hand unit unlocks every feature the day it arrives.
New vs used, side by side
| Brand new | Used / refurbished | |
|---|---|---|
| Price | Full RRP | Typically 20-60% less |
| MagSpeed wheel | Pristine | Electromagnetic, ages negligibly |
| Battery (USB-C) | Full cycle life | Slightly reduced, still days per charge |
| Software features | Full Options+ / Flow | Identical, free download |
| Receiver included | Yes, in box | Check listing; Bluetooth works without one |
| Carbon footprint | New manufacturing | Reuses ~80% already spent |
The five-minute checklist before you pay
- Confirm it is the “3”, not the “2S” or original. The MX Anywhere 3 charges over USB-C and has the MagSpeed metal wheel; the older Anywhere 2S used micro-USB and a notched plastic wheel. Ask the seller to read the model from the underside.
- Test the MagSpeed wheel mode switch. A quick press should toggle between ratchet and free-spin. If the previous owner reports it stuck in one mode, that is a software setting, not a fault, but confirm anyway.
- Check both side buttons and the wheel tilt. These thumb controls are the parts most likely to feel mushy after heavy use.
- Ask about charge-hold. Does it still run a full week off one charge? A battery that needs charging every day or two is the one warning sign worth pricing in.
- Mac or Windows variant? There is a “for Mac” colourway, but any MX Anywhere 3 pairs with both platforms; do not pay extra purely for the badge.
You have more protection than you think
When you buy from a business seller in Australia, even a second-hand one, the Australian Consumer Law still applies. Goods must be of acceptable quality and match their description, and those guarantees cannot be signed away by an “as is” line. If a used MX Anywhere 3 arrives with a dead wheel or a battery that will not hold charge despite the listing saying “fully working”, you have a clear right to a repair, replacement or refund. Buying through a marketplace with buyer protection adds a second safety net on top.

Red flags to walk away from
- “Wheel rattles or grinds.” The MagSpeed wheel should feel smooth and weighted; grinding suggests internal damage that is not worth repairing on a mouse.
- Won’t hold a charge for a day. A genuinely tired battery turns a portable mouse into a tethered one.
- No mention of how it connects. If a seller cannot confirm Bluetooth pairing works and there is no Logi Bolt/Unifying receiver, you may be buying a unit that needs a separately sourced dongle.
- Cracked shell near the USB-C port. Charge-port stress cracks tend to spread; inspect the close-up photos.
- Heavily worn coating with no price discount. Cosmetic wear is fine, but it should be reflected in the asking price.
Frequently asked questions
Does the MX Anywhere 3 need the USB receiver, or will Bluetooth do? Bluetooth works fully on its own, so a unit sold without the receiver is still completely usable. The receiver (Logi Bolt or Unifying, depending on revision) is handy for machines without good Bluetooth, but it is optional.
Can I still use Logi Options+ and Flow on a second-hand one? Yes. The software is a free download and is tied to the device, not the original buyer, so every customisation and the multi-computer Flow feature works straight away.
How worn does the MagSpeed wheel get? Very little. Because it is electromagnetic rather than a mechanical ratchet, there is no gear to wear flat, which is exactly why this model holds up so well on the used market.
Will it track on my glass desk? The darkfield sensor is designed to work on glass at least 4mm thick and on glossy surfaces that defeat ordinary mice, and that capability is unaffected by age.
The bottom line
The MX Anywhere 3 is built around a feature, the MagSpeed wheel, that barely ages, paired with a sensor that does not degrade and a battery that is cheap to live with. That combination makes it close to an ideal second-hand buy: you pay a fraction of new, you keep every premium feature, and you spare the roughly 80% of its lifetime carbon already locked into its manufacture. Run the five-minute checklist, favour a seller who answers the wheel-and-battery questions clearly, and you will likely never feel the difference between yours and a boxed one, except in what you paid.
