Question: Does this mouse help prevent cramping in your hands?  I work on the computer a lot and get fatigued fingers and hands.
Document: Comfort wise this mouse is quite pleasant. I've used it for long hours at a time and my hand doesn't cramp up and my fingers don't get sore quickly from clicking a lot.Only problem I have with the mouse is that it can be a bit laggy at times.
Bought this mouse to replace the smaller mice I bought for my daughter's smaller hands - this one is perfect for my larger hands. Your hand rests on it perfectly, and you don't get any pain in your hand/fingers when using.
I'm happy with this mouse. Could be even used for some casual gaming, as it has some extra buttons and a nice scroll wheel. My only qualm with this and my illuminated logitech keyboard I bought was that sometimes getting both to pair with your computer can get hiccup-y. Sometimes just switching the little receiver usb thing can help, along with other troubleshooting. Once they connect though, it's smooth sailing. Good battery life... would recommend!
I use them all the time when on the web for flipping through pages and even when I am navigating through my folders and files on my hardrive. I don't know how I got along without the feature. I even tend to miss it when I am at work and don't have that feature.The size is very nice and fits my hand well. I feel I have larger hands, thin but long fingers. The mouse has good response as well. I like the small size of the USB receiver very much.
It is a long story for this product. I first bought one on Bestbuy during their Thanksgiving sale, it was great I would say, since my boyfriend stole it from me within three days and he just kept it. I decided to get a new one b/c I was in desperate need for a good mouse that could help me with my work -- so I got it here.
I tried everything. Restarted my computer, did multiple reinstalls of the driver, changed batteries etc. The troubleshooting guide on the Logitech website offered no help (that is usual with most FAQs). Finally I downloaded the stupid Logitech setpoint software and installed it. It still did not work but then I found the Unifying function that allows you to pair a new device and used that and the mouse started to work. Yay!
Upon a recommendation from a friend who never had a problem with this product, I purchased it, hoping that it would help solve my cable management issue behind my computer. It seemed to work fine for a bit. Not exceptionally, mind. But it did technically function. At the same time, I was using a Logitech wireless keyboard. After a while, the keyboard and mouse started to cut out  for several minutes at a time, seemingly at random. So I set them to use different adapters.
I bought this mouse to see if it would help with my wrist pain since I spend a substantial amount of time on the computer. Although the feel is nicer than the standard HP mouse that came with my computer, the mouse does not work at all. It has trouble getting traction on the mouse pad and has almost no range. Unfortunately, I was out of town when the short 30-day window expired, and now I'm left with a $30 worthless piece of junk that I can't return.
I love this mouse.I bought a new Dell computer with a wireless mouse and hated it. The action on the clicker was too stiff and if I used it a lot my wrist would get sore.This Logitech has a light action clicker, and a great feel  on your hand when you use it.
I replaced an old Logitech wireless mouse with this one. This mouse definitely does the Logitech brand a lot of justice. The mouse itself is your basic high quality no frills wireless optical with minimal bells and whistles. No extra buttons or weird design to get in the way. Fits very comfortably in the hand, flows well, etc. The receiver is very compact and easy to use for a desktop or laptop computer (with a handy storage compartment inside the mouse itself), and the battery life is outright astonishing.
Answer: Should help.  I'd also do some of the exercises in "Treat Your Own Carpal Tunnel Syndrome" too to help avoid problems.
