They are good on the moon but not much chop for anything else.
But they do a great job on the moon! Here in the west we use them at society meetings and school nights and you can get a big group of people gathered around the monitor in a social atmosphere and point to exactly what you want to show/explain on the monitor and none of this to-ing anf fro-ing that used to go on and not be sure what you should be seeing. We often wonder how we used to get on without them. Yes they are cheap but they can be fun.
