I've owned several of these over the years. They will honestly last about 2-3 years before they start having a "double click" issue (the button will register single clicks as double clicks every so often). However, during those 2 years, it's been one of the best and most responsive mouse I've ever used, and is able to work on different surfaces. I've tried other mice on the market and always ended up returning them and buying one of these. It's priced well enough to warrant purchasing a new one every few years if you can get it on sale.

I chose to buy M525 as a consequence of balance between price and quality. Magic Mouse is a little expensive for me to purchase. M525 is compatible well with my Macbook pro with Retina. I feel very comfortable to use it. No problems till now.

his Logitech Wireless mouse is unquestionably the best mouse I've owned yet. My previous mouse was also a Logitech, although a rather inexpensive optical model. After several years of use one of the buttons was very nearly worn out, but apart from that the mouse worked quite well. Considering even Logitech's base model offers that level of quality, I have no doubt I'll be using this mouse for years to come. For starters, it's more responsive than my previous mouse. It takes less physical movement of the mouse to click what I want on the screen. It's also slightly smaller than mouses I'm accustomed to, being a laptop mouse, which makes it easy to stow away when traveling. The scroll wheel contains "more grooves per millimeter", which means it's easier to scroll through webpages, as the wheel movement is quite fluid and without the slightest resistance. The box claims the mouse can work on any surface except glass and mirrors, and I've certainly found this to be true as I often use the mouse without a pad. Since the mouse operates on 2 AA batteries, there is an on/off switch as well as a sleep mode to save power. The USB receiver is small enough that there's no need to remove it from the laptop, as it fits almost flush into the the port with just enough sticking out to remove the device. If for whatever reason you choose to remove the receiver between sessions, there is a slot to safely store it within the mouse next to the batteries. I've enjoyed this mouse so much I'm currently using it with my desktop computer. Highly recommended.

I love this mouse - bought this to replace an old one that had become glitchy. It's no gaming mouse, but for everyday use it is great. My last mouse had a clicky wheel, this one doesn't - I almost took it back, but I thought I should give it a try and now I much prefer the free wheel. Battery life is good - 2 batteries rather than 1 (the first thing I look for), it's fast and accurate and heavy enough to really feel you control it. I have the unifying receivers on each computer and laptop so I can take my mouse with me - it's a small thing but I can work much faster when I don't have an unfamiliar mouse.

Compact. Long battery life. Easy to handle. Nice design and contour.
