Summary: I don't know how you don't like this product. I sit in front of a computer every day for 8 to 10 hours. I have tried every mouse, keyboard combination to improve the ergonomics of my workstation and this is the only mouse I have found to work.
Summary: It worked well while it worked. just after the warranty expired the left click button became very difficult to press. I do not want to buy another one because this isn't the cheapest mouse out there. But I did enjoy it while it worked.
Summary: I have a problem with carpal tunnel syndrome in my wrist and this mouse is the most comfortable thing I've used in years. I spend virtually all day every day using a computer for my job and I've noticed a significant improvement since I started using this mouse.
Summary: This mouse was a bear to operate. And by bear, I mean it was like trying to get an actual grizzly bear to operate your mouse for you. If you have come across a grizzly bear and asked it to do some remedial computer tasks, then you know what I mean!
Summary: The wheel lost its functionality after using it for about 4 months. I had been a happy customer until then. Without functional wheel, I felt like a caveman trying to move my cursor to the right of the screen and scrolling.
