Preliminary be said: For purists and / or occasional users of this Presenter is perfect! The presenter has a good tactile feedback of the keys, the most necessary functions (Laser Pointer, in front, back, black screen buttons, presentation end) and an already supplied, very smart receiver. The receiver is smaller than the in the picture (such as a small mini Bluetooth receiver - it projects only a few mm from the USB connector out). Smart because the receiver is housed in laser pointer and is held firmly by a magnet in it. Plugged in the PC he looks barely out - well solved! Establishments, the Presenter with a simple AAA (Micro) battery - how to get them in any supermarket for cheap money. A small pouch to accommodate the presenters is included here, as well as a battery. In previously tested some presentations as a student I can so far only positive things. Haptic the presenter feels after rubberized plastic, to touch even with slightly sweaty hands. After I had seen the pictures and so have read that a conventional battery comes in use, I was a little afraid that the presenter could act too large and thus attract attention - a rather unnecessary worry. Not by the feel, but any more than from about three times the price of the Logitech Presenter - From the build quality of the presenter is not enough to the Presenter Logitech zoom. So if you occasionally need a presenter, and thus do not want to spend so much money, here is super served - a more than strong buy recommendation!
