Contour Design RollerMouse Red Wired - Wired Ergonomic Mouse for Laptop and Desktop Computer Use - 2.4 GHz Ambidextrous Computer Mouse - Mac & PC Compatible

First one I ordered from Amazon was a dud, could not control the mouse and it jumped all over the screen. Finally after trying on a few different computers and user, sent it back and then immediately ordered a replacement which works flawlessly. It's pricey, but worth it if you are having wrist/hand pain or poor ergonomics as I have. Before purchasing, I experimented with putting the wireless mouse trackpad on the middle of my wrist rest up against the keyboard to mimic this design, and it immediately relieved some of my strain. The RollerMouse works even better than my makeshift set up because the rollerbar is much easier to control with a very light touch, and the double click button is invaluable. I just got the replacement out of the box and am typing this review. Feels like my typing speed is faster and using the wheel to control vertical page scrolling is very nice and much easier than clicking the arrow, I realized this when I got arm pain just from reading webpages without typing anything -- the clicking and scrolling and using the back and forward arrow was strenuous.

This is my second RollerMouse Red. I was first prescribed this in a workstation ergonomic review after a workplace injury in which I injured a nerve in my neck. I also have spinal stenosis. This mouse, combined with an adjustable keyboard tray and keyboard tray arm (that bring my mouse and keyboard down to "lap level") allows me to keep my elbows low and resting right right next to / above my hips at all times while I work on my computer. It has saved me from so much pain and fatigue. It's a very expensive tool, but it's a lifesaver! I left my first Rollermouse Red at my last job, as it did not belong to me. Purchased a used one online for home use and, just recently, got a new wireless RollerMouse Red for use at my current office. If you need one of these and cannot afford a new wireless or wired one, look for used wired options, they are much more affordable and - generally speaking - will only need a deep cleaning to work again. If you have pain at your workstation, it's ideal to get an ergonomic workstation assessment from an expert before you start buying equipment. That said, as someone with compressed / injured nerves in my cervical spine, this tool has been a lifesaver for me!

I have had chronic hand pain since 2012 (when I was 21 years old) that doctors have been unable to diagnose. Using a conventional mouse at my job as a software developer became so difficult and painful, I was desperate for a solution. I tried a sideways mouse, but that type of mouse still required the device to be shuffled around on a mousepad, which is hard on the wrist.I found Rollermouse Red and decided to purchase it despite the steep price tag. After 2 years of use, I can say the price is definitely worth it. This mouse has made it possible for me to continue working with less hand pain than if I continued using a normal mouse.Pros:-The roller allows cursor movement with just your finger tips, rather than requiring gripping and excessive wrist movement.-Because the mouse sits in the center, it allows switching between both hands, which can prevent strain on your dominant hand.-Again, since the mouse sits in the center, I no longer have to reach for a mouse on one side or the other. This has reduced strain on my right shoulder that I was experiencing along with my hand pain. This also greatly increases efficiency with my work, considering my keyboard is right there up against the mouse.-I love the physical buttons and the scroll wheel. I use all of them regularly. The copy/paste/double-click buttons are extremely helpful in my work. The buttons have great tactile feedback, and their placement works well.-The mouse is decently heavy, so it won't slide around.-The wrist rest is comfortable.Cons:-Moving the cusor accurately with this mouse does take some getting used to, which can be frustrating at first.-When the roller reaches the end of its bar, the cursor will slingshot to the side of the screen. This can get annoying if you're not watching where the roller is. Don't know if there's any real way to fix this in future designs.-I sometimes wonder if a roller with less width would be better. My hands are fairly small, so it can feel like a chore to move around such a large roller if my hand pain is flaring up.-The roller itself doesn't have very tactile feedback for clicking. This isn't a big deal since there's a left click button as an alternative.-Transporting it can be kind of annoying because the mouse is rather large. Its box protects it well, but it's too big to fit in an average purse.-It's difficult to keep the little crevices of the mouse clean.Overall, this is an extremely well-designed mouse that helps prevent repetitive stress pain in ways a typical mouse cannot.I would also like to mention the excellent customer service I received from Contour. 2 years and 2 months after purchase, my Rollermouse Red started having irregular cursor movement at times. It forced me to put a conventional mouse back on my desk as back-up, which was bringing me more pain in my hands and shoulder. I tried cleaning the mouse with compressed air and installing the official software, with no success. I found on Contour's website that the product has a 2-year warranty, which meant mine was barely outside of it. I decided to try contacting Contour anyway through their online form, asking for any possible solution to the behavior.I received a response in a few days. The representative suggested removing the roller and cleaning underneath it. They gave me detailed instructions on how to do this, along with pictures of each step. As far as I could find, these instructions were not on their website; it might help other customers if they did post it, now that I think about it. Anyway, my point is that their response was incredibly detailed, even though my mouse was outside of the warranty period. Cleaning under the roller seems to have solved the cursor movement problem, allowing me to continue working with less pain. I am very grateful for Contour's professional customer service.
