Query: Better than Conventional Mouse?

Before using this mouse, I had a lot of pain in my wrist and fingers from heavy computer usage in the office (9 hours a day, 5 days a week). Initially, this mouse virtually eliminated the pain that I had in my wrist and index finger. But after a month or two of use, I developed new pain in different parts of my hand. So I switched back to a conventional mouse. I switched back and forth with this mouse and a conventional mouse every couple of weeks for a few months, but stopped switching when this mouse suddenly stopped working. Now, I use a conventional mouse and do hand and wrist exercises (I found a great video online but can't remember where I found it)daily. The exercises have helped more than anything else. In my opinion, save your money and don't buy this.
