Mandalor_Ian 3 I really liked using this product for my slides and I found it worked very well. However, if left open, the software sometimes causes serious slowdown on a computer (I'm using a new Macbook Pro). It seems to conflict with other programs. This is a minor problem as the software can easily be closed.The BIG problem is that after 3 months, it isn't responding at all. It lights up to show it's charging, but does nothing when the buttons are pressed. It's now a junk item which is shocking considering the price. I am not happy!
