"This one claims that 2 AA battery could last three years."
"Battery life is solid."
"I've only had to change out the batteries once in that time so it actually does live up to its claim of 3 year battery life on average."
"The battery finally died after constant use in my undergraduate and masters... the stock battery lasted more than double the advertised 3 years."
"Good battery life and only needs one battery to operate."
"Very long battery life (+ the SW shows the battery status) means you rarely have to worry about batteries dying when traveling, etc."
"In the entire time I've owned this mouse, I've only needed to replace the batteries ONCE."
Cons:
"The batteries are supposed to last up to three years but I would guess with daily use it might not last that long."
"Already had to replace the batteries too!"
"Three years of battery life seems like an extreme stretch; so far I've only managed six months before the critical battery alert."
"Yet, lately (only about 2 months after purchase) it seems to be having the same troubles as the old one that sucked batteries."
"It's been my experience that these things are battery hogs."
"I will love it if I get a year or more from the batteries."
"The battery life has proven decent, in that I purchased the mouse in June 2013 and so far the supplied batteries have only started to display a critical power level alert in January 2014."
Ergonomics and Design
Pros:
"Very small and portable."
"I am a lefty and have small hands. I find this to be a great fit."
"The mouse has a nice rounded shape and seems to work on just about any surface that I try it on."
"The mouse fits very well if you have average/medium sized hands, particularly if you use a claw style grip."
"The mouse is small without being too small; I find it fits more comfortably in my hand than most 'full size' mice do."
"It fits nicely in my hand and is very ergonomic."
"It fits a small hand beautifully and makes computer use so much easier."
Cons:
"I am upset it stopped working so quickly."
"The mouse is not very ergonomic (price) but the biggest problem is the lack of compatibility with the existing 'Logitech USB Unifying Receiver for Computers and Laptops'."
"The feel of the mouse is bad."
"The mouse felt very small and unsubstantial in my hands."
"Too small, was not able to get used to it."
"Not the best comfort fit for your hand, since its smaller."
"It's too small so not suitable for long use."
Performance and Connectivity
Pros:
"I am on my fifth work laptop and third job with this mouse, and it's great!"
"Even 7 years later, this mouse is still in excellent working condition and I cannot recall any time it did not work for me."
"Amazing optical tracking! The cursor does not run away."
"Tracking is smooth and works on every surface I've tried."
"The device connected quickly and worked well."
"Performance wise this mouse is very good."
"This mouse allows me to select small details with ease."
Cons:
"I had this mouse for less then a month and for some reason the cursor no longer moves smoothly."
"Failed after 3 months. No significant drops/shocks."
"The control is 'sloppy'. You don't feel like you have good control either for scrolling or move movement (on a nice mouse pad)."
"The range of the mouse is too small so if you use it too far away from the computer [...] the mouse won’t be working properly."
"The scroll wheel on my M525 has failed 2 years and 4 months into its life."
"However, since my M305 eventually died within a few months of exhibiting similar (and increasingly worsening) behaviour, I will be keeping a close eye on this mouse to make sure it isn't dying already."
"The mouse worked fine for about 2-3 weeks, then it stopped working."
Additional Features
Pros:
"The side is a more rubbery texture."
"The USB dongle is very small and hardly noticeable on the side of my laptop."
"You can have up to 6 Unity devices working off of one dongle."
"One feature I didn't expect when buying this is that the scroll wheel tilts left and right."
"The back/forward feature is very handy as it utilizes the mouse wheel's lateral movement."
"The 'Unifying receiver' is small yet it can connect multiple Unifying compatible devices."
"The Unifying Receiver and the associated software allow up to six devices, such as mice and keyboards, to be paired up with one Receiver, a real plus when faced with a paucity of USB ports."
Cons:
"The mousewheel has almost no traction."
"The scroll wheel clicks to the left and the right, which is a fantastic feature."
"However, the scroll wheel (while marketed as the most precise) just scrolls too freaking fast, and the middle-click button becomes nearly impossible to use because of that."
"Does not support backwards and forward on Mac computers."
"Model 525 specs says Mac compatible; it is not."
"Logitech does not supply supporting software for Linux."
"Clicking the scroll wheel button was a bit tricky to learn how to do because the scroll wheel spins so freely."
