The product is made in an overseas factory. While the actual design may have come from a Microsoft employee. The way things are manufactured today we know everything is outsourced. My minor carpal tunnel hasn’t really flared up since switching to this new mouse. So far I’ve had little pain when using it. But the unit supposedly is ergonomically designed. You would think that this would lead to wrist discomfort. I have seen others that are bigger but this mouse is not small. The picture doesn’t really detail the monster size of this model. Makes sense since the other one was for a notebook. This mouse is much larger than the one it is replacing.
I recently purchased this Microsoft Natural Wireless Laser Mouse 6000 to replace a wireless notebook mouse I had been using.
