This is so easy to set up, because it sits firmly on the floor, is raised easily and stops where you put it. Aspect ratio is 4:3 but the bottom edge is only about half-a-metre from the floor, so if it stands on the floor the top half of the unit makes an excellent widescreen. If you want to make use of the whole 4:3 screen the unit is best placed on a table (in a room with a high enough ceiling!) It is suitable for a home room because, unlike a tripod, the footprint is small (although long), and you don't need to raise all the screen for a small group of people. It's equally fine in a large hall. A lot of different people are going to be using the one I bought, so I have stuck a yellow label on the handle supports on the box (the only place a label will stick on the box) with memo TURN FEET - BEFORE OPENING. And stuck a green label HOLD THIS on the handle you grip to raise the screen. That's all the instructions needed. Stable, idiot proof and it gives a great picture.
