Contour Ultimate Workstation Red Wired - Includes RollerMouse Red & Balance Keyboard - Wired Ergonomic Keyboard & Mouse Combo - Compatible with PC & Mac Computers

I was over using an external mouse. While this is NOT an inexpensive purchase and VERY WORTH it! I Less strain on the wrist, forearm. And I've gotta be saving time keeping both hands on the keyboard. I did purchase

I first ordered this keyboard and mouse combo after having a surgery that left my left arm immobile. I still had movement in my fingers on my left hand, so I was able to lift my arm and still type and work productively. It was a godsend for me with my disability. I highly recommend it for people with carpal tunnel issues or tennis elbow from mousing with a separate mouse. It is ergonomically situated to ease pain from constant keyboarding and mousing.

I loved it, but for my injury, it did not work

This is the mouse Everyone should use -- you never have to pick up your hand to go to the mouse. I had ergo evaluation at large company and they asked me to try it for a week. I called them 2 hours later and told them -- they better order me another one because I'm not giving this back. Honestly, less than 2 hours and I was hooked... HUGE saver for hands, wrist and movement back and forth between keyboard and mouse. I just wish my 15+ year old one would break so I have excuse to buy an new one.. it works fine but I wore out the cover on padding and it flakes alittle-- still works perfectly.
