convenient but limited

say it is really a mini-projector, with a limited zoom (it takes a step back and have a interesting size image), limited lighting (thus projection in a dark room especially if you want a great picture), but which can be very convenient because of its size and its various inputs.
The price is also related to the product so we are not disappointed but as I use normal projectors every day, I can see the difference.
you have to buy depending on the use, here will not be a movie projector
