Dishonesty and false advertising as only the Chinese know how. And Amazon condone it.

Don't expect home theatre quality from this cheap item. The brightness is nothing like 100 lumens, let alone 4500. There is no provision for changing the size of the display. The fan is very noisy and the keystone correction is laughable, as it merely swings a lens, putting either the top or bottom of the screen out of focus if the projector is anywhere other than directly level with the centre of the screen.
You get what you pay for, but Amazon shouldn't allow their suppliers to make such outrageously inaccurate claims.
