SP400 Smart-Pointer (Silver) 2.4Ghz RF Wireless Presenter with Mouse Function and Laser Pointer

the item was excellent. dealer sent the item promptly and i am very happy about it.

This little gadget is the ultimate thing for presentations. Works like a charm -- tested by me under windows xp and on an iMac, tested by a friend under linux. All three tests: just plug it in, wait a sec and both pointer and disdrive are operational. The two control buttons on the pointer function as PgUp/PgDn buttons, which ensures maximal compatability for most applications. Range is about 15 metres -- usually far enough, but for big screens / big halls: make sure the receiver is positioned strategically.
(The combination of a gigantic projection and a laptop placed 2-3 mtr to the side of it, ment the opposite side of the screen was on the edge).
