Another Great Mouse from Logitech

Logitech M325 Wireless Optical Mouse

All good things must come to an end. Considering the amount of abuse my Logitech V450 Nano wireless mouse suffered week in and week out, it’s not surprising that it eventually stopped working. On the other hand, it did last more than 4½ years – longer than a lot of laptops these days. They were not easy years, either, entailing heavy work with precision 3D modeling software and also an owner who regularly eats lunch at his desk. Messily.

So when it did come time to replace that V450, I didn’t bother looking at Kensington or Microsoft or any of the others: I headed straight for Logitech’s catalog to see what had replaced the V450. The answer is a Logitech M325 Wireless Mouse, and it’s (pretty much) just like my old friend.

Here are some basic specs for the M325:

The mouse operates on two AA batteries; not included. Logitech claims “up to” 18 months' battery life, but we all know that’s just a guess. On the other hand, I only remember changing the V450 batteries a time or two, so more than a year sounds reasonable. It operates under (almost) any flavor or Windows or iOs, as well as Chrome and Linux.You’ll need a USB 2.0 or 3.0 port for the receiver (in case you don’t know, a USB 3.0 port [usually] has a blue plastic insert and a 2.0 has black).The body's about 3¾” x 2¼” x 1½”, slightly smaller than my old V450. It’s ergonomically shaped to fit the hand with a rubber grip notched on both sides for the thumb, and can be used either right- or left-handed. Logitech calls the scrolling "micro-precise," and I have no argument there. The 2.4GHz wireless signal is highly reliable: I’ve never experienced a dropout or delay, even from across the room.The eensy-beansy nano receiver is called a “unifying receiver” because you can run as many as six USB devices on a single receiver… assuming they’re Logitech devices, I think.

Like its little predecessor, the M325 is a two-button mouse with a scroll wheel that can be programmed to act as a third button (for Linux fans, among others). For everyone else, the wheel operates as a forward/backward switch for web browsers; just tilt the wheel to the right or left, respectively. You can download Logitech drivers to enable an extended set of mouse features, but I prefer to use it as a standard “dumb” mouse with the Windows default mouse driver. If you want to run multiple devices on the unifying receiver, you also have to download the unifying software. Haven’t tried it…

That receiver is one of Logitech’s Nano receivers, so called because it’s a tiny (about ½” x ¼” x ¼”) chunk of plastic sitting on a USB plug.  It’s so small I never bother to unplug it, even when stowing the laptop for travel – it sticks out perhaps a quarter of an inch. If I do you want to disconnect and store it, the receiver tucks into a dedicated slot in the battery compartment, which also turns the mouse off. You could also leave it plugged in and turn the mouse off with its bottom-mounted switch. There’s a tiny green LED on the top to show the power’s on, which turns red when the battery’s low – aat which time the mouse seems to have another week or two of battery life.

Special programming features: If you download SetPoint, the M525 will end up with additional functions. By default, the wheel’s programmed to scroll the current window right-left with a wheel “tilt.” If you press and hold the wheel, you get software zoom to enlarge/reduce the current window. Tilt and press functions can be re-assigned to several other actions, like volume control for yout speakers.

Life with a Logitech M325:

Installation is easy, since it's plug-n-play. My laptop runs Windows 7 64-bit,, and the mouse worked immediately upon installation.
Download: The download software is massive, which is the  reason I didn’t bother with it – I’ve used it on other machines and don’t find that it adds that much to my experience. I have no need for the unifying software, so ditto on the no-download.
Physical stuff: The receiver only projects about 0.25" out from the USB port so you really can plug it in and forget (though maybe not so much if it’s on the side that rests on the bottom of your laptop bag).
Range: It's a minimum of ten or twelve feet from the receiver, at least with fresh batteries. I always like that for presentations, because I’m a bit of a roamer.
Surface Sensitivity: It works fine on a plain countertop, rubber mousepad, magazine surface, newspaper, cloth, and wooden desk without any tracking problems. Like other mice (mouses?) it's pretty useless on shiny or monochrome surfaces.
Portability: Though decidedly compact, it’s also pretty dense. It’s probably worth the extra ounce, though.
Buttons: Some aftermarket mice have extra programmable buttons under the thumb and ring finger for additional controls; if you're used to them, you'll not find them here. If you're not, you probably won't care. I find that the mousewheel is super-sensitive, allowing me to scroll line by line instead of the noticeable jump of some cruder mice.

Is it really Ergonomic? Well, that might depends on your tastes: the M325 is kinda chunky, but it’s still a little small for large hands. If portability isn’t your driving need, a larger mouse might fit your hand somewhat better.

Overall: A nice little mouse with few shortcomings. Logitech sells sexier mice, but they cost more than this one’s $30 price tag . I’d recommend the M325 for medium to heavy use, though not for cursor-intensive pastimes like CAD or gaming; and I especially recommend it for travelling, where its small size and Nano Receiver will be a blessing. Oh – and replacement receivers are available from Logitech, so you can literally forget the receiver as well! Summary PLUS: tiny and tough even while it's sensitive MINUS: some of the software downloads are a little "much" WHAT THEY'RE SAYING: I liked my last couple of Logitech mice so much that when the latest one died I didn't bother to look at anything but the Logitech M325 Wireless Mouse.
