Trying to find a pointer that was under $100 and capable of working on PC and Mac seemed unachievable until I found this device. Having purchased it I was then sceptical that it would deliver. Well it well and truely delivered. It not only worked on both types of computers and laptops. It worked incrediblyu well. I was able to walk around a large auditorium with a large crowd and many obstacles and still just click the buttons and see the slides change. I can only highly recommend this item, it does everything it says it does and for an excellent price. Also I will recommend Mighty Ape as they were quick and efficient at delivery.
