Oh, and the the back & forward buttons on the side for web page surfing are pretty nice too

Awesome, comfortable grip, no lag, sturdy buttons.

Great button placement.

It feels well made with quiet buttons except for the wheel, which is flimsy and cheaply made with a lot of free play

The programmable buttons were great, took a bit of getting used to, but once learned they gave me quite an edge while gaming

To say I love it is an understatement: I work in IT, and it is absolutely wonderful to remotely access a person's computer and be able to scroll from side-to-side with the scroll wheel (everybody sets the computer up to their own standards so there is vast variation).I also love the forward and back buttons on the side, and this mouse is mighty ergonomic with a good heft to it

Also love the fact once you download the app onto your desktop you can customize the 2 buttons on the side as well as what happens when you press the scroll wheel

I am constantly clicking the right button accidentally which I have never had a problem with.

Personally I hate those buttons but to each their own, I couldn't find a similar one without them

Has left and right scrolling which is pretty cool and the two buttons on the side

I love the side buttons on this mouse!

I pried it up, but the button remains sticky.

The right click button is so sensitive that merely laying your middle finger

My work laptops right button in the touch

The back/forward buttons on the side are great, with a nice clicky feeling

Love the programmable buttons with Logitech's software.

If you want change from the standard left click to a right click button be prepared for daily frustration.

but as a 3rd button it's kinda insensitive

Very easy to set up, very easy to use, ergonomic, the buttons on the side are easy to reach and the sides are slightly

I have two big complaints though:1) the back/forward buttons are hard to click

It becomes hard to do anything... such as click a button or select the right cell in Excel

The other day, the mouse started acting up and when I would try to right click, it would act as if I was HOLDING the right-click button instead of just TAPPING it

The "left click" button, the only one I use is also inconsistent

Very smooth and distinct buttons.

no communication issues, no interference with the other mouses in the office, 1.5 to 2 years battery life, has place for the dongle inside the mouse, very ergonomic, perfect size, perfect weight, perfect resistance on wooden surface, it almost never get stuck because of dirt on the sensor, invisible laser, it works well on every surface except transparent glass, the roller (middle button

but it turns out that this mouse, the one I bought, the right click button just didn't work.

Not jerky, goes where I tell it to, good button response.

Awesome, comfortable grip, no lag, sturdy buttons.

After 8 months using the mouse the middle button stop working

Fits perfects in hand perfect button for back and forward on pages

Also like the back and forward buttons.

We'll see how long it lasts before the click buttons stop working

My biggest complaint - and this is important - is that the left click button stops working about 1 year into standard use (including working from home)

The buttons hardly work

And having 7 buttons is a big bonus.

Feels good to use, love the extra buttons on the side.

Customizable buttons and sensitivity work well

It's a cheap-o product that causes your cursor to stall and freeze
