A4 TECH NB-90D Review

Good Points
Battery free wireless optical operation. USB battery free transmitter. Good weight and size. Good looking in black and silver. Inexpensive at GPP 12.00 - paid for by savings on rechargeable batteries!

Bad Points
None - although some users may consider the 9 inch diameter pad a restriction on mouse movement.

General Comments
The best wireless mouse I've owned because it overcomes the problem of battery power and having to recharge batteries at inconvenient times.
The USB transmitter, 7cm in diameter, is attached by a wire to the pad on which the mouse must be operated. The transmitter and pad are silver and black in colour, matching the mouse.
