Hello everybody :) I have my presentation for my diploma topic held and have to say, with this pointer I was Super happy! It was what I wanted to do! + Forwarding: super + Lazerpoint: super + Practical! + Easy to use + Is super at hand + Is detected directly from the laptop I was happy !!! The batteries were there. Just do not know the hold, but extra batteries should how long you have always with you;) If a presentation is important;) It's also really cheap! It is worthwhile in any case and you can certainly make good use of in the future!
