Logitech Performance MX Wireless Mouse (Discontinued and Replaced by MX Master 2S)

My initial experience with a Logitech Performance MX mouse. First thing, it is a mouse for the right hand. Whose right hand I asked myself, surely not MY right hand. I wondered if the hand that it was designed for was an alien, with absurdly long triple jointed fingers and an unusually shaped palm attached to an arm that swept horizontally at an odd angle. I continued to gripe and complain to myself until the phone rang and I tended to business. Several minutes later I found myself back at the keyboard and mouse and realized that I had transitioned to the new mouse without thought. Yes definitely some alien brain manipulating handiwork here. To install it, I put the rechargeable NiMH AA battery into the battery compartment. The battery included didn't impress me much and it was also completely uncharged so I put in a better class of battery that I happened to have at hand. I did notice that the charger cord had a nicely sculpted 'grip' on it. That was a nice touch, along with the faux-leather pouch to contain the accessories: charger, charger cable and receiver extension cord. I was happy to see that the battery compartment has room to hold the *tiny* USB dongle that plugs into the PC and provides the wireless receiver. The 'UNIFYING' technology allows one single dongle to server multiple Logitech devices. As I already had an existing Logitech device and a dongle, I didn't bother to put it into the PC, I just left it in the mouse battery compartment and was happy that it had a safe place where it wouldn't get lost. The Logitech setpoint utility was already installed on my Windows 7 PC at work and it recognized the Performance MX right away. I noticed that *unlike* some other mice that need to be 'woken up' and discard the first few mouse movements, the Performance Mouse is instantly responsive. Maybe that is the 'performance' part along with the 1500dpi resolution and darkfield dual optic sensing. The mouse tracks smoothly and reliably. I was surprised that the extra buttons were well placed and not subject to unintentional activation. I had myself unintentionally become accustomed to the mouse in a short time. I used the mouse for the rest of the day, and before leaving work I packed it up to take home. After packing up the MX, I put my original mouse back on the desk and was shocked at how... dull and unresponsive the old mouse felt. The MX mouse installed into Windows 8 at home without a problem, and again was nice to use. The Logitech setpoint software running in windows 8 has some options that work differently than when it is run in windows 7. For example, the ability to assign window flip/ aero flip/ application switcher doesn't seem to work on Windows 8 when assigned to one of the additional buttons. I haven't contacted Logitech about this. In the end, I really like this mouse, it works well, it is cordless, responsive and comfortable. I might even get another one for work. It is a really nice mouse. Follow-up: since my initial review on January 4, 2013 it is 9 months later (Oct. 2013) and I'm still using this mouse. It is still a bit large for me and I tried a very similar styled 'marathon mouse' for smaller hands for a while but it just didn't perform as well. This performance mouse needs a recharge every couple of weeks but it is easy to recharge it by plugging in the USB cable. This mouse can be used while recharging, or left plugged in overnight. The mouse has held up well after lots of use, many hours a day with minimal signs of wear, a bit of shine on the left mouse button press area but all other parts showing no obvious signs of wear. The teflon slider pads are ample and in place. Best thing about this mouse: it tracks well, every button click registers when it should and it is responsive. Still a really nice mouse.

RE-UPDATE 6/7/17: Unfortunately this mouse DIED ABOUT 3 MONTHS AGO AFTER TWO (2) YEARS OF DAILY USE so I bought the MS Mobile Mouse 4000 but I missed this Logitech Mouse because of all the features and comfort detailed below in my original review and update. This model Logitech Mouse was truly the best mouse for a desktop PC that I've ever owned. My only disappointment was when it started being erratic, skipping, and got so bad it was no longer usable. For travelling I also have a Microsoft Wireless Notebook Presenter Mouse 8000 and it is 7 years old and still going strong so the 2 year life of the prior Logitech Mouse is kind of disheartening. Hopefully this new one will last longer. For a more complete review keep reading. ORIGINAL REVIEW & UPDATE HERE: I just received this mouse today but my first impressions are very good. It does have a certain "feel" built in which I think has to do with the thumb position being more comfortable. For the record, I've been using what could be called a travel mouse, the MS Presenter 8000 which cost considerably more than this one but also has a built in pointing laser and other features. I originally used it just for traveling but then my MS desktop keyboard/mouse kit started giving me trouble like not receiving the mouse's wireless signal so skipping a lot. So I switched to the Presenter mouse but then begin to like it due to its small size. But I'm an old dude and my hand doesn't work as well as it use to so I figured it was time to get a more comfortable mouse and when I saw the reviews on this one I went ahead and ordered it. So far I love it, it's very comfortable in my hand and I like the idea of being able to change certain mouse buttons to something else like I did with the old MS mouse. For one I like the scroll button to be the "double click" as sometimes my left click finger doesn't cooperate with my brain and I have a heck of a time doing a double click. That problem solved with this new mouse I still haven't figured out a good use for the 6th button which defaults to "application switcher". Since I rarely use the Windows 8 Start page and prefer the desktop apps this isn't a good option for me and I wish it had more choices to choose from. I've settled on "minimized current window" until I find some other one I would use more often. It would be nice if I could use to go to my favorite URL or most commonly used program. If you need a new mouse and/or have carpal tunnel syndrome, arthritis, or some other hand problem this is the mouse to get. The extra $ it cost are well worth it and if your desktop is glass or a surface that a regular mouse doesn't like (like some wood grains) this is advertised to work on everything. The only "downer" from what I read is the battery life which lasts from only a few days to a week or so by some of the posters. We'll see how that works out. They should have used two AA or AAA type batteries so it would last longer. I also have the Logitech lighted keyboard and getting rid of one of the USB plugs was nice since I now have 3 items running on the "Unifying" receiver, the lighted keyboard, the mouse, and the touchpad which I rarely use. The keyboard will run for over a month on a full charge and the touchpad on standby about the same or longer so I wish that was true of the mouse. UPDATE 11/6/2016: Well I've been using this mouse quite a while now and must admit this is the best mouse I've ever owned or used. It's just so comfortable and for me fits my hand perfectly. I have arthritis in my hand and it doesn't ache from using this compared to others. Again, the ONLY con is the battery life but since it can still be used while charging that isn't a big deal. The micro USB plugs in the front end of the mouse on an upper angle which keeps it from dragging on the desktop so you barely knows it's there. Buy this mouse, you won't be disappointed. I also have the companion keyboard and it's great too with it's backlighting and much longer battery life.

これより新しいMX MASTERが出ているが、持ちにくいので、左手用のサブ機にしかならなかった。仕事で一日中持っているので、このマウスが最高に操作しやすいし、違和感や疲れが少ない。

Entrega: Rápida, confiable, segura, el pedido me llego antes de lo esperado y en buen estado, gracias. Opinión: Es un excelente mouse, un poco grande a lo esperado (pero los botones son grandes, si eres de mano pequeña aun así te servirá) tiene muchas funciones a programar para su uso (descarguen el programa de la pagina oficial logitech), lo recomiendo al 100% para aquellas personas que se dedican a trabajar en diseño, programación o están todo el día en la computadora, es muy confortable y ergonómico (tu mano y muñeca te lo agradecerán), cumple con todo lo que promete en las reviews que dan. Aparte los materiales se ven resistentes y elegantes, así que no solo es funcional si no también impresiona con su aspecto.

Darkfield sensor allows you to use the mouse on any surface, I am using it on fully transparent glass table. It's a good mouse for users who use mouse for cursor control. Forward button may be little difficult to reach for someone with short thumb. Some reviews have mentioned mouse double clicks with a single click but have not noticed that as yet on mine.

La souris Logitech MX est tout simplement géniale. Elle offre une excellente prise en main et est très confortables. Les touches raccourcis sont parfaitement positionnées et facilement reconfigurables au besoin. La souris est très précise autant sur un tapis de "Gamer", une planche de mélamine ou sur la jambe de l'utilisateur. Je l'utilise régulièrement pour des présentations debout et je peux interagir sur l'écran en glissant simplement la souris sur ma cuisse et sa fonctionne parfaitement. Sa forme offre une prise ferme permettant son utilisation en se déplaçant sans risque de l'échapper. Elle est excellente autant pour le travail de bureau quotidien que pour le "shooter gaming". Je la recharge environ une fois par semaine en la laissant allumé toute la journée et l'utilisant environ 4 heures par jours. Sa prise de recharge permet l'utilisation sans contrainte lorsque le fils est branché. Je recommande absolument cette souris de qualité à tous. Livraison rapide avec Amazon Prime.

購入して約１３年、もう外見はボロボロですがいまだに愛用しています。 性能といい大きさといい文句のつけようがありません。 最近接触が悪くなってきていますが一応一個だけ予備を所持しています。 後継機種があるそうですが全くの別物でがっかりしました。 なのでそのストックも開けるのがもったいないくらいです。
