    No more elbow pain

    Posted by Banker Mark on Feb 15th 2015

    Using a standard mouse for 20 years, the muscle near the elbow of my lower arm ached after each day of work. After switching to this mouse, the pain is now gone. My employer paid for one and I bought another for home.

    At last I have found you!!!!

    Posted by Rona on Aug 6th 2013

    I have been looking for this mouse for almost two years. I was lucky enough to work for a large oil company as a buisness partner contractor, These Ergo evaluations were done often. Not only ergo evaluations, there are work pace breaks which allow you to just sit and do what the WPB displayed on your computor monitor. Bypassing this break would send an alarm up the chain and if this became a issue there were disiplines for this. While part of this company. I not only learned why it was so imortant I became a firm believer in Ergonomic Evaluations and Work paced breaks. Near the end of my life with this company, I was evaluated and offered a ergo mouse just like the one above. I thought wow they make anything, it looked crazy to me... it wasnt two days later and I thank god they do because this is the only mouse that I can use everyday 10 hrs a day and not feel the pain that I feel from every other mouse I have found. I ended up setteling for Performance Mouse MX, nice and pricy and it helped but there is nothing for me like the Evoluent vertical mouse. So thank you I am excited to get mine. cross my heart this story is true.

    Mouse made a huge difference!

    Posted by Yvonne on Apr 22nd 2013

    In addition to getting the vertical mouse, I ordered an ergo keyboard from Kinesis and my discomfort went away. Just by changing the position of my wrist when holding the mouse and typing made a huge difference. The combination of both worked for me. I would definitely recommended the vertical mouse. It is worth the price to prevent future injury and since I type for a living, it is worth the investment.

    Works great!

    This ergonomic vertical mouse has made my right hand feel so much better. I was getting tension and soreness in my right thumb pad from the old mouse upon repetitive clicking or holding the thumb down. This vertical mouse relieves the thumb pressure on those movements and is much more comfortable and in a natural position. It took a few weeks for relief to show, but things are much better now. Thanks!

    Changing Over Was So Easy

    Posted by Shari on Mar 25th 2013

    I really like my new vertical mouse. It was so easy to make the transition from a regular mouse. My wrist, arm and hand definitely feel much better. We purchased my boss the larger-sized wireless mouse. The only improvement I could make to the smaller mouse is to have it available as wireless also. That would make it perfect. Thank you.

    Saved My Career!

    Posted by Bill on Mar 7th 2013

    I'm at a keyboard for at least twelve hours a day, and had begun to suffer severe pain in my elbow and lower arm. I began to worry that I would have to stop working with computers and change careers. When I changed out to the Evoluent Vertical Mouse, my pain was immediately diminished and within a month was gone completely, while I was still working the entire time!
    Even if you don't suffer any pain, I can't recommend this mouse highly enough.

    Evoluent Vertical Mouse Small

    Posted by Laura on Oct 29th 2012

    I"m really enjoying the Evoluent Mouse! It has helped my wrist pain tremendously. Took about a week to get used to. Can't wait for for a wireless version of the small to pack with my laptop.

    Human Solutions quickly responded to a question I had before making the purchase.

    Evoluent Verticl Mouse 4 Small

    Posted by cbencan on Oct 28th 2012

    I really like this mouse, the arm position is perfect, no more nerve pain in my arm and wrist. I don't program it, just use top and bottom buttons and the wheel. I hesitated to try this mouse (used a roller ball mouse for years) thinking that my arm pain would not improve because you still need to move the mouse around for the arrow position. But this mouse together with Evoluent's Mouse Friendly Keyboard = no pain anymore!
    My only suggestion is to add a roller ball at thumb position.

This product comes standard with a 2-year warranty.
