A4 Tech NB-30 BattryFREE wireless optical mouse

Juniper Foo | Nov 09, 2004

If a mouse is accurate and cordless, with long battery life, what more could you want? How about no battery? Once you get past doing a double take on the spelling of BattryFREE, the idea is pretty cool. The key to liberating this input device lies in a special USB mouse pad that is RFID-enabled, utilizing the principle of electromagnetic induction. What frees that rodent unfortunately also ties it down. So just don't ever lose that mouse pad.

Device: Wireless optical mouse
Basic specs: 1 25 x 16cm USB pad (RFID-enabled), USB connector, user's guide, big u-shaped wheel scroller, 2 status LED lights
