Noticed it is mainly for those that are right handed.

Great mouse it fits my hand well and has great wireless connection.

For example, when editing photos in Adobe Lightroom, I attempted to move the adjustment sliders on the right hand side by increments of 2 (which I was able to do with my previous wired mouse), but because it wasn't sensitive enough to pick up my slight movements I could only make changes of 5 points or more

Fits my hand well and works as designed.

This worked out nicely though, since my wife is right handed and I am left

I highly recommend buying their products - you will be in good hands.

It honestly hurts my hand to try to grapple this thing over long period's of time

The MM057 is a very comfortable right handed mouse not suitable for left handed operation and the 2nd is a symmetrical mouse that can be used in either hand with a little practice

Nice for right-handed user, ergonomically good grip, sensitive and fast thru all CPI settings

My favorite part is how naturally your 3 finger (ring finger) on your right hand lands perfectly on the curved part of the mice designed for it

I gave a one star only because I ordered a left handed mouse and got a right handed one.

Fits my hand well and works reliably

Fits my hand well and works reliably

Personally, I don't know why it's so difficult for right-handed people to simply create a mirrored replica for left-handed people

I have fairly large hands and preferred the slightly larger Anker

This mouse has a great weight, good hand feel, is well made, and it seems like the delay isn’t too bad

I have big hands, but despite that, I like smaller mice

The mouse itself has a very good build quality and fits hand ergonomically making it very nice to use.

but you dont feel cramped to use it if you have larger hands like me.

Good for everyday use, fits my hand well and will go into sleep mode when not being used saving on battery life without having to shut down computer.

Fits the hand well and the battery (not included) , a AA, is easy to change.

It's a perfect mouse for people with right hand as their dominant hand.

For the cost of the mouse, it has a great ergonomics and fits hand great

This mouse has a very comfortable feel, is reasonable and feels comfortable in either the left or right hand.

I read the reviews before I ordered this mouse and it is awesome, but it is ergonomically designed for a right hand

I have large hands - didn't like the feel and definitely don't like the sleep mode after 7 minutes.

It would feel like my hand is "resting" more.

Easy to use and ergonomic design fits my hand well.

However, if you have hands with a small palm, the groove for the ring finger isn't very comfortable after hours of use

It fits my hand great, and I appreciate that it “hibernates” in between uses to preserve battery life

Smooth, fits hand well, haven’t had any issues.

The MM057 is a very comfortable right handed mouse not suitable for left handed operation and the 2nd is a symmetrical mouse that can be used in either hand with a little practice

After two days of trying to use this, it's really hurting my hand because the grooves on the right of the mouse get in the way of my ring

I still gave this product a perfect 5 stars because I am used to using right-handed tools

They fit perfect in smaller hands as well as larger hands.

I have larger hands, and would prefer a larger mouse

It's a tiny bit asymmetric, just enough to be super-comfortable in the right hand, but not enough that it'd be hard to use left=handed.

It fits my hand well and is easy to take with me when I travel

Fits my hands well, works great, I love the cordless mouse!

good hand feel....seems pretty durable to

A bit small even for my smallish hands

The wheel stopped working right away and the mouse fits only the right hand so it is not possible to switch to the left hand when the right hand gets tired.

Fits my hands well, works great, I love the cordless mouse!

The mouse fits his hand well and the slight shaking doesn't seem to affect the functionality of the mouse.

Mouse works great......except is for a right-handed person.

My hand was getting fatigued and achy after using my laptop touch pad and mouse stick.

So far though the mouse works great , fits my hand perfectly and is very comfortable

IT just naturally fits my hand really well

Fits the hand, easy to maneuver.

This mouse fits my smaller hands very well while still leaving a little bit of room for larger hands

Works as intendend, and fits my hand like a glove.

Lightweight, very responsive, and fits my hand very well

Fits hand well, works well

Fits hand well, works well

Fits my hand well.

It fits his hand well and works great with his computer

I’ve been using it for a few days, it fits my hand really well, and it’s very comfortable

The ergonomic design fits my hand perfect

I had gotten tired of using the mousepad and having limited mobility, and when I used a mouse with a wire it also came with limited mobility as well as it feeling a bit chaotic.

It makes it easy to grab and there is no fumbling as to where the buttons are when you don't have time to stare at your hand

Works exactly as I hoped it would

I’ve never written a review but in this case I will because I’m confused as to why this product has so many positive reviews

Works exactly as you expect it to.

there was a lag at times and didn't work as
