This little machine really works well. It has a bright lamp, and best of all it is small and light. I bought mine because I was tired and having to struggle with machines at the sites were I give presentations - they never have the right cords and there is always a 15 minute delay in trying to get it the projector to work. I have a MacBook and plugged this in, 30 seconds later the image is up and running. It comes with everything you need to get going - all cords and cables are included. I only needed to have the adaptor for my Mac but that came with my laptop. Having my own machine is making my life much easier and my presentations now become the focus rather than the wrestling with the projector. If you do a lot of talks or presentations I suggest you get one of these - a nice small machine at a good price.
