The weight of the mouse is "just right"

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

Smooth touch, lightning fast receiver speed, good weight

But (and this is huge), it has great weight

The weight of the mouse is great as well, keeping it grounded to your mousepad

it is well weighted (I find many too light).

It is the perfect weight in my hand, very comfortable to use (I use it every day for my 8hr work day)

Nice ergonomic feel, good size and weight, and smooth operation

It's also a good standard sized mouse, with a decent weight

Comfortable in the hand, easy set up, has a nice weight to it

Does what it is supposed to do very well!Comfortable size and the best part is it has a good weight and feel to it! not light and flimsy!

Great feel - great weight - lasts a long time with one set of batteries

The side\thumb buttons are much better and have a good click weight to them

I like that it has a little weight, has auto sleep and the rest of the

well I like it and use it daily for both bruising and photo edit

I like the two buttons on the side for back and forward when on a browser, very nice.
