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.
Junk... Don't Waste your $. Manufacturer can't be contacted, warranty claim ignored.

Summary: The mouse operated for about 45 days then went completely dead. I changed USB ports, batteries and rebooted numerous times. I tried to contact the manufacturer but there has been no responses to any posted inquiries for over a year.
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.
