My partner uses a Microsoft Natural Wireless Laser Mouse 6000 (well actually, one that came with the keyboard and mouse combo...) and it's beginning to get weird on us (it drains batteries really fast, both good alkalines and rechargables). We'd replace it with another, but Microsoft seem to have discontinued the product.
Can anyone recommend a similar styled 'ergonomic' mouse? Ideally rechargeable, or with long battery life.
I use a Logitech Performance Mouse M950, which she finds isn't tilted enough and set off her wrists, and the 3M joystick mice go too far and set of her elbows and shoulders.
