Logitech - Performance Mouse MX - Black

This is by far my favorite mouse. I love the way it fits my hand. I feel it is a good ergonomic fit.

My trusty Logitech M705 Marathon mouse started having a problem with left click. So it was time to replace it. This mouse looks good. But it is almost one inch longer than M705. I have medium sized hands. They are too far away from the front edge of the mouse. So each click takes a bit of extra pressure. It is also noticeably heavier - my hand muscles are a bit sore as I am a heavy user. I think this is because of the Darkfield technology. They need to offer a mouse with the same old technology and rechargeable battery in the same smaller form factor.

Best. mouse. Ever. Best. mouse. Ever. Best. mouse. Ever.

I've tried a lot of different mice, ones I've bought/receved elsewhere and ones that my husband has. I received this one as a Christmas gift from my husband and I don't think I'll ever try another. The position it places your hand in is very comfortable! It takes a couple of days to get used to, but it's very much worth the initial weird feeling. I have some painful issues with my thumb joints and this relieves SO much stress from them. It's really nice that you can plug the mouse into the computer to recharge the battery and still be able to use it. I love this mouse and I definitely recommend it to everyone, but especially to people with thumb joint pain like me. It will make using a computer so, so, so much more comfortable!

I did a lot of mouse shopping to replace one that was starting to have trouble with the scroll wheel after many years. It is difficult to replace something to which you have grown so accustomed to the fit and feel. Other than the obvious stuff on the product description, here are my notes.. . PRO - I really like having the "thumb button" in the base, where you press down with the side of your thumb. My old mouse had that. It can be programmed to do things like be a mute button, or switch applications (default behavior), or whatever you need. This one also has a "Zoom" button on the side, but that can also be reprogrammed for any feature. I currently have it programmed to behave like the middle-mouse button, because then I never accidentally scroll a bit when I try to click the middle mouse button. It is rechargeable via the included USB cable. That's nice. A charge lasts quite a long time, too. I also like the movement. Very steady and predictable. CON (but also a PRO) - The curvature is really narrow for my thumb. It's more like it was made for a finger rather than a thumb. It was almost a deal-breaker. However, once I started to get used to it, and stopped trying to nestle my thumb all the way in, it wasn't too bad. Some people might think of it as a gentle hug. On the bright side, it makes it very easy to lift the mouse, such as when you are doing a multi-step movement to get your cursor all the way across two monitors, etc.

Bought this Performance MX mouse to replace my 2006 version of the Performance MX mouse about two months ago. During that interval, Logitech decided to omit all of the functions I mentioned in my "What's not so great" comments. Why? Not sure, but normally for budget reasons. My mouse, is a very, very, very fine mouse. With two kids in the yard, life isn't very hard because of it. With Darkfield Laser Tracking, it will track virtually anywhere - even over glass. Rechargeable battery is a nice touch - on/'off switch incorporated in mouse. Logitech Unifying technology permits multiple compatible wireless devices to be used via one receiver. No need for multiple USB receivers. Nice touch. The scrolling has a two -function button that can be depressed to initiate warp speed scrolling or much slower page/line by page/line scrolling. One clever feature allows you to view all open Windows on the same screen; you then may select the Window you wish to view. Very handy, I've found, when I have a lot of Windows open and need to recall what they are. So, I guess Logitech Giveth and Logitech Taketh away, when it comes to features, buttons, bells and whistles. Frankly, I found the omitted volume and mute controls much more useful. I only hope that this mouse is as indestructible as my previous mouse which literally has been dropped from Miami to Afghanistan and still survived; Until now. RIP Would be a 5 if it was Made in America.

Wonderful mouse, only contoured/ergonomic mouse best buy had in the store. not quite as good/comfortably of a contour/fit as my old IBM mouse it replaced, but it makes up for that in other ways. It has a button that allows the scroll wheel to freewheel instead of being geared to only move the screen an irritatingly small amount at a time, so you can navigate anywhere on screen or in a document with ease, just remember that if you move the wheel too fast it wont stop on its own and u will have to stop it with a finger b4 it goes past your spot you want it to stop at or you will have to scroll back up again. it has built in zoom buttons and another button where your thumb rests that looks like its made to resize the current window but I haven't tried that one yet. unlike my old IBM mouse, this mouse is wireless, it comes with a "Logitech Unifying Adapter" that can recognize the mouse and several other devices(still don't know why it needs to recognize other devices yet) unfortunately it doesn't charge wirelessly but it can be charged by a wall outlet or USB port either/or. The charge also seems to hold for a minimum of 2-3 days up to a week or two depending on how much you use it. and there is an on/off switch underneath the mouse so you can turn it off when not using it so it doesn't keep using up its charge. it also has something called a "darkfield" sensor that seems to be able to track the mouse on any surface just as promised so that a mousepad isn't needed. only minor issue I sometimes have is when scroll wheel is freewheeling instead of being connected to a gear, if I tilt the mouse or the laptop desk accidentally my screen will move when I didn't want it to and sometimes the screen will move downwards by itself and I will move it back up only for it to move right back down and I will have to hold the scroll wheel still or keep moving it back up or lock it down to the gear to get screen to stay still. overall though its a wonderful product, a little pricy but worth it.

This is my second laser mouse from Logitech. My first was the original MX1000. It was a great mouse that was easy to use and had great accuracy. When it finally decided to start and die on me, 10 years later, I was wondering if I was going to be able to find anything that would be comparable. Lo and be hold... Logitech came through yet again with a worth upgrade to my original. I love this new mouse! I get to use the same charging cable for it as I do for the keyboard, phone, Kindle, and a host of other things I use as well at the same receiver that my keyboard has. As I have had a button heavy mouse before there was not really much of a learning curve. The battery life is pretty good, it will last for about a week before needing to be plugged in again. I can use it on ANY surface I have on the desk. I was a little worried about it working with my Rocketfish gaming mouse pad as it is is a metal mouse pad, but it works great! I would highly recommend this to anyone looking for an accurate and easy to use mouse. The buttons come programmed with a basic set of commands. You can change them around if you want but for what I do the ones that are already there work just fine. So if your looking for a great mouse this is it.
