NB-57D Wireless Mouse
Model: NB-57D Wireless Mouse - Release Date:May.2006
A4Tech just released another new wireless mouse for Royche retail in Korea. The NB-57D is a Battery-Free Wireless Optical Mouse. When we say Battery-Free, we mean it… no battery is required. This solves one of the biggest problems with wireless mouses, no more battery running out on you while you’re playing your favorite video game or browsing the internet. It all works via a process called “Magic Magnetism,” which is an apparent A4Tech cocktail of electromagnetic induction and RFID technologies bundled into the kit. Simply put the mouse gets the power from its USB connected Mouse pad. The NB-57D mouse delivers an 800DPI sensitivity and features 7-buttons plus a scroll-wheel which can be endlessly mapped to shortcuts via the included 2X-Office software. According to AVING, the NB-57D is yours for right around 20,000 Korean Won or just about $21 — that’s an amazing deal for the buck.
