the product has arrived within days and capable than Windows 7 Professional 64-bit Plug & Play. I have connected the device, Windows has recognized all at once and I could without problems Present.
If someone uses the program Song Beamer, I can pass on here the same, that it works flawlessly even over this program.
The distance between the signal output and the signal input are in my presentations about 5m, and I had so far no crashes or sudden signal loss etc.The integierte laser pointer is also a nice feature, but this is the price that least. :-)
Lie down for a Presenter 30 is overcome, but it's an investment that pays off.
