Wow my hand is in MOUSE HEAVEN.

Not HUGE, not terrible, just it forces your hand to sit at an awkward

It is bulkier than the Apple mouse and not so stylish, but it fits my hand well and is very comfortable to use, which is more important to me than style

The mouse itself is sizable (to a degree) and ergonomically designed for a comfortable hand fit that incorporates the hand’s natural tilt.

but this product fit my hand more and comfortable!.Amazingly Smooth!

It's forms to the RIGHT hand very comfortably (not for leftys)

I NEVER use my computer, or any of my electronics with dirty hands, and despite my best efforts; I can't keep this dang mouse looking decent

This is a larger mouse but it fits my female hand well

I like the fact it will work with more than one computer and the shape seeks like it fits the hand

Charge lasts forever, doesn't hurt my hand to use, precise & fast.

Finally, ergonomically, did not fit my hand well and became uncomfortable quickly - and my hands are not small.

I think this is in relation to how well the PERFORMANCE MOUSE MX fit my hand, it was almost effortless

I feel sorry for left-hand minority group getting left out but everything is designed for right-hand dominant group

I'm a full sized adult male with decent sized hands and it's barely adequate for me.

It fits my large hands well, comfortable, and it's solid.

Actually... if it also warmed my hand when it's cold... that be amazing

It will take a while for your hand to get use to it much like buying and wearing brand new shoes.

That being said, if you have smallish hands, this would be an ideal mouse

Requires you download a program from logitech to use the mouse- Back/Forward buttons are so far back that I need to contort my hand to reach it with my thumb- scroll

Mice are like scissors, though, we just have to learn to use them right handed, but still for fine detail work on my own computer I prefer using my left hand.

I previously owned an MX Performance Mouse, which is very comfortable and fit my hand well

It fit my hand fairly well and the various touch points and surfaces were comfortable.

Repeatedly doing this is going to definitely hurt my thumb and hand

So far the 2S fits the bill, as well as my hand (I'm 6'4 and have large hands).

Because I promise you no matter how clean your hands are, you will discolour this thing because of the extremely poor quality and/ or sensitivity of material they went with

I have to twist my hand around the mouse a small bit to roll the wheel (solidly, not a light roll), and toggling the side button up and down requires the twist of my hand to that side to support the mouse as I'm pressing the button

My hand doesn't feel fatigued or sore after hours of use, as happened with most other mice

The mouse is offered for right hand use only

it fits my hand like a glove!

I was intimidated by multi-button mouses (mice?) but found my hand getting uncomfortable during long work sessions

Fits the hand well and is accurate.

This mouse feels great in a large hand, far more comfortable than the magic mouse, but very very laggy, tried to adjust all settings, system and with the logitech options app, still lags regardless of what I do

Great hand feel, my hand doesn't feel tired or cramped after hours of use everyday

I've been looking for a durable mouse which allows for tactile precision and also doesn't fatigue your hand after prolonged use

is very big and thick, not easy to carry around, perfect for desk and my hands never hurt after long time of use (My old mouse used to hurt my hand).

Only one point to criticize (same as it's little brother) is that there are no warnings if the battery is running low

a while later it doesn't work as it's supposed to and now it's nothing more than a ineffective paperweight.

Perfect! A+++

Work exactly as I expected or even better!!!

Since it's a laser mouse I am able to use it on a glass table top as well as on blankets and wooden tables.
