One of the most important features of a mouse (to me) is what I call "the back button", which is oh-so handy when surfing the web.

Of the many wireless mice, this one responds well, stays connected, and battery lasts a long time, Comfortable, nice extra features, and good value for price

It's shape is perfectly ergonomic, it's got forward and back buttons, and my favorite feature - the scroll wheel you can push to the sides to scroll sideways.

Best feature is the suitably measured click pressure for both left and right mouse buttons - presents just enough pressure to "not" be overly sensitive and hasn't double-clicked once in error!

It works great, fits my hand, and the battery power saving feature is ingenious and works great - just slide a switch on the bottom to the left, showing red color, and your battery is no longer drawing any power

Excellent performance, great features.

good features

A very nice feature for traveling.

The forward and back buttons are a nice feature

Great mouse, download the logitech options program to get some cool features

Just the right size, full featured and well positioned scroll wheel, back and forward click buttons.

Love the scrolling features and the back and forward buttons for page turning and comparison shopping.

I like the design and features of the mouse but not how it responds to commands

Also, an important feature is that the button clicks are pretty quiet - they're quieter than all the other mice I have used in the past.

There is a nice little strip of plastic built in that when you pull on it, the batteries pop up, this is a nice extra feature for changing batteries so you don't have to jam a butter knife in there to get them out, then slip and rake your finger with the jagged edge and pathetically explain to your wife how you managed to cut yourself with a butter knife and watch as she hides the scissors

It's a shame because I love the horizontal scrolling feature of this mouse and the last

The buttons on the left side are a great feature.

I really like the feature that allows the usb dongle to be stored inside the mouse

The software runs constantly in the background, but isn't too bloated (averages about 3 MB of RAM usage, 0% of CPU usage).Overall, a great budget multi-purpose mouse with a few good features added in.

The Dell mouse is very good, but not as comfortable to work with, or as full featured, as the Logitech mouse

The programmable buttons on the mouse are a nice feature.

The logitech software has some good customizability features, including tweaking the functionality differently for different programs

I do like the feature that shuts off the mouse when inactive, although I still do turn it off when I'm going to be afk for more than 10 min or so.

I have a lot of check boxes I have to click and as fast as I can if I want to complete my assessment and move to another job.

I really can't find another mouse that works as

No complains as of yet

The USB keeps disconnecting during use for a second or two...really disappointed as I've had mouses that lasted *years

Still works as if brand new 3 Years later.

Only minor problem I have is the scroll button in the middle is not working to well as it did before, but might probably be the laptop, or I need to change battery soon

This was a replacement for an old M510 which stopped working as it kept double clicking automatically

Works exactly as Id hoped

Was great while it performed but after several months it was not as responsive as at first.

I did not do anything to damage as it was always safe on my desk

Apparently the contact beneath the left click (possibly the right as
