Logitech M325 - Battery life, Receiver and Sensor

Our Score:


A simple-to-open panel in the M325’s base gives access to a single AA battery. This means that once the provided alkaline battery is drained, it’s easily replaced with an affordable, long-life rechargeable such as an Eneloop. Either way this rodent won’t have too much of an impact on the environment, as Logitech claims a single battery will last up to a whopping 18 months!

Obviously we couldn’t test this claim if we wanted to bring you our review anytime this year, but we have found the company’s battery life claims to hold up fairly well in the past. There’s a handy little off switch on the M325’s base too, if you won’t be using it for a while.Logitech M325 2

Also behind the battery panel, you’ll find the slot for storing the USB Nano receiver, which plugs into your laptop or desktop PC to allow the mouse to communicate wirelessly. To be honest we would have preferred an exposed slot you can just stick the dongle straight into, as found on the Microsoft Wireless Mobile Mouse 6000, but overall it’s a minor quibble. As seems to be the standard on high-end wireless peripherals these days, the receiver is tiny, measuring 18mm from tip to tail. When plugged into a USB port, the protruding bit is a mere 7mm.

As is typical for the majority of Logitech’s wireless gear, the M325 uses 2.4GHz RF technology rather than the more complex Bluetooth, so it also offers longer range, and we had no trouble using the mouse from over 10 metres away. Thankfully, and this is a major benefit over rivals, the receiver is of the ‘unifying’ kind, which means it can be used with all recent Logitech RF keyboards or mice. Just ‘program’ the device into your single receiver using the appropriate Logitech software and viola, one-for-all.

Only when we come to the mouse’s sensor do we find our first disappointment: it uses an 1000dpi optical sensor, rather than the newer and more accurate laser variety. Let’s put this into perspective for a second though. On most surfaces and for most tasks, optical is more than adequate. After all, this isn’t a gaming or performance beast. But with the likes of Microsoft’s 6000 rival using BlueTrack, which can track across virtually any surface with better accuracy to boot, it is a limitation worth keeping in mind. We would love to see a mobile mouse that utilizes Logitech’s Dark Laser tech for tracking across glass.

They do one already - Anywhere Mouse MX http://www.logitech.com/en-us/mice-pointers/mice/devices/6536

I've got one and it's perfectly small enough for a mobile/laptop user

Have this mouse for 1 week now.. It is absolutely wonderful to use. Incredibly ergonomic and fits great in the palm of your hands. This has always been the case with Logitech mouses, unlike Microsoft mouses which not only feel worse but also aesthetically look ugly. The scroll is incredible....if you hold the mouse stable with 1 hand and literally spin the scroll wheel as fast as you can with the other hand, it will accelerate the speed scrolling down in excel as fast as it can. The accuracy is also smooth and very nice to work with. This is truely a recommended product! Hats off to Logitech!

With the Microsoft Wireless Mobile Mouse 6000 selling for $69.95 and the Logitech M325 selling for $29.95 these mice are not "rivals". In this regard your research is lacking. Therefore, I would advise readers to totally ignore this review.

Considering we reviewed the MS Wireless Mobile Mouse 6000 over 2.5 years ago (!) I don't really see your point. At the time of publication (JAN 2012) our comments were valid. £15-ish for the Logitech and £20-ish for the Microsoft rival.

In October 2013, it seems the Logitech M325 is still available and very affordable. The MM 6000 has clearly been retired and replaced with a newer model.

This was/is a bad product, mine worked 1 day then refused to be recognised, Ltech sent me a new "unifying" receiver which worked for a few hours then dissappeared upon reboot later? endless downloads drivers uninstalls config attempts blah blah, Iv`e learnt to never trust a wireless mouse again but moreso never buy a Logitech device again :(

Is this really optical? Looking at the bottom of the mouse while it's on, I see no telltale signs of an optical sensor...
