Logitech mice are some of the best in the tech world. Very durable, the laser puts up on nearly every surface, and they feel nice in your hand. I highly recommend this mouse. I tend to get 8-9 months out of each battery change as well.

I've always been a fan of trackball mice because there is no need to move the entire mouse around when mousing. It was a no brainer to me that I should buy Logitech. I'm a huge fan of their other products. The only mark against it is that they don't include the "hyper-scroll" wheel like in the MX models. Add that to the Trackball and it'd be perfection.

This keyboard and mouse combo has to be one of the best I've ever used.

I want to start off letting you know that I have been a long time faithful Logitec consumer.  When my last mouse from them went out however, I decided to look around.  I had a mouse keyboard combo and would have just purchased a new mouse if it weren't for the fact that it would have taken my second of three USB ports.  When I started looking, I wanted a keyboard that would fit my need for compact, low-profile keys, quiet, and a more streamline, but unique design.  The keyboard meets that and more.

First off, the keyboard has a great feel to it, and the keys, despite a few reviews, are very quiet.  It feels like I'm typing on an ergonomic laptop.  There are a ton of extra function keys that I haven't bothered to program yet, but from what I've read it will be as easy as installing the keyboard was.  I plugged the USB in, and it was rearing to go.

The USB dongle is very small and out of the way.  And best of all it doesn't emit any light, so all of you nocturnal users can rest at ease.

They mouse is the last piece to review, and it has a number of high points, but a small fault. First the bad, it is a little loud when you use the main left and right click.  It is something I totally got over when I looked at the rest of it.  The BlueTrack technology really makes it so that the moue can be used on just about every surface.  The wheel is smooth, not loud and clunky like previous logitec mice.  and the mouse comes with two extra side buttons.  On the Mac they automatically set up for Dashboard and Show all Workspaces.

The whole deal was a great price, and if I had to do it all over again, I would definitely purchase this combo.

I bought my first Revolution shortly before they went off the market and were replaced by the Performance Mouse. The Revolution was hands-down the best mouse I've ever had, for these reasons:

- Solid performance
- Super-handy thumbwheel (apparently I'm in the minority of buyers who really liked this feature)
- Comfortable and ergonomic
- "Pincher" feeling between the index finger and thumb helped me with accuracy.
- Great for work
- Easy to customize buttons for each application
- Free-scrolling wheel with independent clutch to toggle the "chunky" scrolling
- Sharp looks
- Good quality.

The Revolution was replaced by the Performance Mouse, which was a minor step down in many ways, but you could still give it a solid A for effort. Then Logitech decided they had to cater to average, non-task oriented buyers so they dumbed down the Performance Mouse to make the Master MX - which is a complete joke and has next to none of the features app and task-heavy users need. Logitech has steadily been axing useful features, upping the cosmetics, and charging the same high prices for junk.

The only drawbacks of the Revolution MX were
- Lack of replaceable battery
- Charge dock meant you had to stop using the mouse to charge it - not an issue for me since it would charge overnight and last all day
- No cord to plug in and use while the battery was dead

I still have two of my old Revolution mice that suffered the infamous Logitech Double Click Death; I'm either going to sell them for parts or hunt up the necessaries on eBay to fix them myself.

These are one of the best inventions since the Internet!
They have looks and intelligence.  With the trackerball being moved by my fingertips I get less wrist and hand fatigue from longterm use of the mouse.  I use one at work too and it does cause curious stares and questions but once you use one and give it a fair try you will be impressed with the agility.  It is easy to clean and doesn't get gunked up like a regular mouse does. The price is definitely right too!

I have been a long time fan of Logitech.  Ever since Logitech introduced their first mouse on the market, I have been buying their mice and peripherals including keyboards and speakers and have never betrayed them.  They always meet my expectations and all the mice that I buy are from Logitech.  When I had a problem in my wrist, known as carpal tunnel syndrome, Logitech trackman tracball literally saved me. It was the first time that I started to like the trackball.  Before that, I had used many trackballs built in notebook computers, however, I had never liked those.  After the Logitech MX Revolution came out on the market, I have been using it ever since.  Now I meet my old savior again in a different shape, cordless with a tiny receiver,  which is the Logitech wireless trackball M570.

My first impression with the M570 was not so great, because of the material (probably plastic) used for it.  I get so used to the top-notch finish of the MX Revolution mouse, the M570 made of sliverly plactic did not impress me.  And the blue thumb-ball looked little strange, since red was the color for the logitech trackball engraved in my mind.  But the thing that impressed me was the very tiny unifying receiver.  The good thing of this tiny unifying receiver is that it is compatible with other Logitech products, so you do not need to carry separate receivers for different mice, trackballs or keyboards.  According to the information on the Logitech home page, the unifying receiver is currently compatible with 5 wireless mice and 4 wireless keyboards.  I am expecting that Logitech will introduce more peripherals using this receiver.

The look and feel of the M570 is pretty similar to the Trackman.  The only difference is the M570 is cordless (I know that there is a cordless version of the Trackman, too).  The M570 is light and fits well on my hand.  The feeling and rolling of the ball is good and the programmable back/forward buttons are great plus.  And the M570 works fine on Mac, too.  The one thing that I like is its long battery life.  The M570 uses only one AA battery and Logitech claims that the battery will last 18 months.  Even if it lasts for 9 months, I would be happy with it.

Now, I have been using the M570 for 2 months now and it just works well.  No problem and no complaint.  I still love the tiny receiver.  It does not stand out too much, so I do not need to care much when I move my notebook computer.  My only gripe is that I wish the M570 was a little heavier.  Other than that, the M570 is a usual Logitech quality product that made me a loyal customer of Logitech.

Love my logitech track ball mouse.. there is NOTHING better for tight desktop space, or just being lazy and NOT wanting to move. they have perfected the ball and precision over the years, and this one being bluetooth and wireless is awesome.  I am able to also have 2 separate mice.  one at work, and one at home, and with the logitech software, I am able to sync both.. so one little dongle in the laptop is all that is needed, and just turn on either mouse and they both WORK at each location.

One of the best products there is apart from lack of product development. I would like some more buttons like those on more modern Logitech mice such as sideways scroll and navigation on websites. Otherwise it's ergonomy is flawless and helps me continue to work with computers, ordinary mice gives me excruciating pain after a time.

At first glance i was amazed at how small it was. Then i took a look at the usb receiver and was even more astonished. This unit takes two AAA batteries and up till now still has great battery life. The reception is equally good with many things blocking the signal, like a couple of rooms away little did i know the cursor was still moving around smoothly with no signal loss. Aparently this mouse has one of the better optical tracking lasers on the market so most surfaces should be ok. Comes with a great black zip carrying case for those who are always on the run. You cant go wrong with this mouse, won some award in August I think for one of the best innovations or some thing like that. All in all you can go wrong with this mouse, its small, stylish, powerful, and not too outrageously priced for what you get, i love it.

Pros:

On off button, small, stylish, usb receiver fits in the mouse itself, great battery life, carrying case, great optical tracking, great reception, good software, good price on amazon that is.

Cons: none yet, maybe that its too small for those with big hands but my hands aren't that big and it is a travel mouse so no cons to date.

Bottom Line:

I think i might buy another one for my dad. 5 stars for this mouse, don't waste your money on the other logitech and microsoft notebook mouses at around 30 dollars a piece this one is perfect. What is an extra 20 bucks for something this good? Got a 8.3 on cnets reviews which is very good, cant go wrong with it get this mouse!

I have been in IT business for 20 years and I am not sure if I can recall using a better mouse.  It has a very good feel and it is very responsive.  Not to mention the awesome price.  Great job Kensington.

No drivers needed in Windows as with most mice products I presume.

This is the third Logitech mouse I have owned and they have all operated perfectly for years. The only reason I got this one was because of the new and improved technology and lighting effects. It is also a bit smaller than the other curved gaming mouse of theirs and I like the ambidextrous feel better. I have had this about a year now and it is by far the best mouse I have ever owned. Cool lighting effects, lots of customization and I have not experienced any issues in the last year. No noticeable delay with use and works great for gaming. Highly recommended.

I have historically used Logitech and Targus mice and keyboards.  I find them in general reliable and durable.  The one exception in my experience is the Logitech LX7 mouse which got flaky about a year after purchase.  This episode took me to the Performance MX.  Lots of programmable buttons!  The Logitech software makes it easy to program the mouse to your liking. Because of the shape, it takes a little getting used to (a few days).  After going through the learning curve you appreciate the shape.  Very responsive.  Not too light or heavy.  If i have any criticism of the Performance MX it is that the rechargeable battery needs recharging every few days - but you can use the mouse while it charging (with a cord).  The recharge time is very fast.  The mouse also comes with an AC charger.  It is a little pricey but it is the best mouse I have ever owned.

Let it be known that Darkfield technology is no joke and for sure is not a gimmick. This mouse works on anything and everything. No need for a mouse pad. Ive compared this mouse to many other mice and where some mice fail on certain color tables and/or mouse pads, the Anywhere MX mouse works flawlessly.

This mouse also has the switchable scroll wheel allowing for the clicks we all need as gamers or smooth scrolling many use for web pages. Just press down on the scroll wheel to switch between smooth and clicks. The scroll wheel also has the ability to scroll left and right. Along with the back/forward customizable thumb buttons on the left side of the mouse. As well as a customizable button on top under the scroll wheel.

Its also very convenient that the included USB dongle allows for unifying technology, meaning if you decide later on that you want to purchase a new logitech branded keyboard with unifying tech you can easily sync it with the same USB dongle already plugged in from the mouse, saving you precious USB ports! 1 USB dongle for multiple accessories!

The build quality of this mouse is excellent, the mouse is not to heavy but not to light, its just right. Fits perfectly in most hands and is very portable as the USB Dongle can be tucked away inside the mouse battery compartment. And speaking of battery, this mouse has excellent battery life.

Now, the reason this mouse gets 4 stars and not 5 is because its not Bluetooth. If Logitech releases this exact mouse in Bluetooth form then it would be perfection. But as it is, when it comes to USB wireless mice it just doesn't get any better then the Anywhere MX! And if you are not in the market for a Bluetooth mouse then technically this mouse gets 5 stars!

I just got the MX Revolution mouse. I have to say it is absolutely amazing. The ergonomics of this mouse are outstanding.

The biggest feature on this mouse is the Micro gear precision scroll wheel. It allows you to super fast through long documents - spins for up to few seconds and zips past pages and pages of content. This, as opposed to, constantly going to the scroll bar and dragging it down. At the touch of a finger, it stops instantly - amazing response.

The best part is that I can still use the ratchet motion of the wheel especially in applications such as Powerpoint. So, the wheel can go step by step through slides.

I am still trying to figure out the battery life of the mouse. The cool thing there is that it shows the battery life in days much like a laptop would.

I have always loved Logitech products but this one beats my expectations hands down. They have taken so much care to build this thing - you have to use it to believe it!

I am going to buy one for my husband too!

This mouse is a five-star product. Enough said.  Do not be misled by always superior and ever challenging geeks. Elsewhere, one writes: I found the mouse to be overly sensitive, even after changing the mouse configurations in Control Panel. The Microsoft Wireless Notebook Optical Mouse 3000 is more precise,he/she writes and concludes: The Logitech v220 is a little bit more ergonomic on the hands, but not by much... Well, I use it for my traveling laptop and most recently I have attached it to my new mini-mini-mini-laptop, my baby-computer Acer Aspire One.  It works great. If its receiver slightly sticks out from your USB port, well, everything will. Only gadgets with Bluetooth technology will not. BTW, I use here a small USB hub, flexible; to it I attached this Logitech mouse AND also my wireless/national broadband USB modem (phone card.)I suspect that overwhelming majority of us do not use their notebooks, net-books, mini-notebooks, baby-computers for major NASA or global warming predictions/projects or medical research, or weapons testing. Neither do I use my baby-computer for working with huge raw files/photographs in Photoshop CS3.
So, perhaps what might be overly sensitive is in the eyes of beholder. Myself, I do not need to change the mouse configurations in Control Panel. V220 is small, works great and if needed -- it fits in my pocket. That is enough. And yes, I know what the Control Panel is.  If you need one, just buy it.

They are just amazing. You wouldn't expect them to work good due to their price, but its Logitech and they never fail to amaze you.

I started using this mouse at work (IT Admin) after my coworker gave me his spare one and after 2 months I HAD to order one for home. It's great for productivity and gaming alike. Plug-and-play under Windows, Linux, and my Hackintosh builds.

Logitech is my go-to company for HID peripherals except for gaming keyboards (sorry guys, those G-keys really mess with my flow) I've been using a G500 mouse for quite some time as well as the K400 keyboard on my HTPC and countless other devices over the years.

My main gripe, which is strictly software related and I will not deduct a star for this: The Logitech software seems to have much more functionality under Windows 7 than under Win 8\8.1. Mainly because under Win 7 I have the option to use an Aero-type application switcher with the thumb button that is reminiscent of the feature you find on Mac OS (the trendy name escapes me right now...) This feature is absent under Windows 8, and the default function is switch DPI... but you may assign the thumb button.

I find myself mistakenly hitting the "zoom" key every now and then but I fat-finger things all the time and have it bound to KP_Enter mainly for ArmA 3. I have fairly large hands (I'm 6' 4" with Stevie Ray Vaughn-esque banana-fingers) so my pinky finger feels like it's hanging on for dear life dragging across my mousepad.... but in no way does it affect comfort level.

Battery life is OK. I plug in the one at the office every Friday before I go home for the weekend. Being able to use it while charging is a major step up from dock-type rechargeable peripherals. At home I just turn off the mouse when I'm done gaming and can eke about 2 weeks of life out of it. Using a standard USB charger is a huge plus in my opinion, since that connector is ubiquitous among my IT colleagues (read: Android die-hards)

The smooth-scroll toggle feature is something that I've been spoiled from after using the G500, and I am ecstatic to see this feature included on this mouse as well. The software goes one step further and lets you dial in how many lines one scroll-wheel "click" equates to which is mega useful.  You really can whip through documents, router configs and weapon slots. Nothing like ending a CS:GO match in front of your nemesis letting your weapons switch wildly before their eyes.  ;)

You won't be disappointed by this mouse. I feel like it aims to please all and, unlike most devices, succeeds at doing so.
