The Microsoft Wireless Laser Mouse 6000's retail package includes the mouse, a mini-receiver, a driver CD, two AA Energizer batteries, and hardcopy documentation:

The Microsoft Wireless Laser Mouse 7000 has a very similar bundle, and it features the mouse, a mini-receiver, a driver CD, a charging base + plug, one AAA rechargeable battery, and hardcopy documentation:

Both the Microsoft Wireless Laser Mouse 6000 and 7000 mice offer the same basic package. Both are easy on the hands and are very ergonomic and comfortable. The buttons are smooth and easy to access, although the Teflon mouse feet might have some problems on rougher and heavier on surfaces like wood. The scroll wheel works as advertised, but is a silent model, with none of the audible clicks that some users like.
