TrustedReviews has posted a review of the Logitech G7 cordless 2000dpi Laser Mouse
The G7 design is very similar to that of the MX518, but oddly enough some features have been removed. But letβs start at the beginning - the new laser sensor. The G7 has a 2000dpi sensor, thatβs 400dpi more than the MX518. However, itβs not practical to use this kind of resolution for Windows work, as the mouse goes all over the place.Logitech G7 Review
