Summary: I bought this as I couldn't face buying another Logitech after having lost two. Actually, I lost just one, but left the other's usb dongle somewhere which made it useless. Or almost; I now use just the laser pointer to entertain the cats. This Trust presenter works without software and has a good range. I found the 'joystick' lacked the fine control necessary for it to be any use as a mouse.
Summary: I guess if you are used to using one of the little buttons you find in the middle of some laptop keyboards to move your cursor around you might be able to use this presenter. I use a mouse, and this gaget was just too tricky to control so I haven't used it in presentations at all. Anyone want to buy it?
Summary: This device is the right solution of travlers which like to have a standard sized mouse. The only fact not yet known to me is the robustness of the fold mechanism. As again in an year or so ... ;-) BTW: Works out of the box under Windows (7/8) and (Ubuntu) Linux (12.04).
Summary: Pros: Well it works. No drivers needed and it's a plug n play to windows XP and Vista (i tested it in both). The buttons do their job so is the mouse scroll. It is small and light weighted. The Laser is good and strong. The mouse or presenter operation can simplify your needs. Cons: The "connect" button is placed in the rear side so usually when i press connect i accidentally press 2-3 thousand other buttons of the presenter.
