Question: How does one move the cursor with the whole mouse or similar to a track ball?
Document: Overall, if you're having wrist pain, you need this mouse. But just be prepared that it moves/tracks poorly on granite, leather, and painted surfaces. Pretty much anything other than my cubical desk or a piece of paper don't work (mouse cursor on screen doesn't move). Not the end of the world, just put a piece of paper under it, but thought you should know. Other than that, great product.
I tried several left handed track ball mice before I purchased a left handed Evoluent mouse at work as an ergonomic alternative to all the right handed mousing. I keep both mice connected to my work computer and switch back and forth during the day to avoid too much stress on either hand. I liked it so much from work that I purchased a right handed wireless Evoluent 4 for my home computer. I love it! My wife is not so thrilled and continues to use the Microsoft wireless mouse.
Unlike other reviewers, I did not wait until I was experiencing pain before switching to an ergonomic mouse.I purchased this mouse because it places my hand in an ergonomically netrual position, and because it may prevent pain from developing in the future. It's comfortable to use, it does what it's supposed to, and it works well.I subtracted one star because the scroll wheel feels a little flimsy & makes an odd squeaking sound. A scroll wheel should move smoothly and *silently*.
My issue is that precision is really lacking. You want the cursor in a particular spot -- it may take you a couple of tries (compared with my old mouse where that was never an issue). Right now, I am using it for basic word processing and web surfing. I had hoped to use it for photo editing.
Very disappointing. I've had mice that could track on the desktops at my workplace for years. It's a surprise to find something this expensive that hasn't caught up to something that basic.
It's really hard to click!! Since the force of the physical click is pushing sideways instead of down (like a standard mouse) you tend to move the mouse to the left each time you click. Which as you can imagine can be a problem. The mouse itself is totally fine, I just can't do this design.
This mouse is great. I have used Evoluent mice since I first developed carpal and had the surgery... I do believe it reduces the stress on the whole wrist and forearm, reducing the likelihood of developing or reactivating CTS.The wireless version goes to sleep when not in use, saving the single AA battery life.
It is very smooth and has no downward/inward sloping edges in which to grip it to lift it. It's like gripping a slippery wedge. So if you scroll off the edge of the mouse pad, the only way to grip it is to move your thumb off its resting position and down towards the bottom edge of the mouse, and squeeze with your thumb and middle of pinky finger - and even then the grip is poor.
When mousing, if you get to the edge of your pad, you want to pick up the mouse and move it over. The instructions tell you to tilt it and drag it, but I found that to be annoying. You can't exactly grab it and lift it up as it will slip from your grip if you don't apply finger pressure (which triggers clicks you don't want). I solved the problem with a bit of bat grip tape.
There is just no good, comfortable way to lift this mouse!I think this flaw is recognized by Evoluent because they devote 1/4 of their short user manual to "tilting" the mouse to move it without moving the mouse pointer. But this is a stop gap measure and works poorly.Compare the shape of the Evoluent mouse with the Microsoft Natural Mouse.
Answer: With the whole mouse. Think of a regular mouse but turned 90 degrees on its side.
