The only disadvantage is When it is connected with the HDMI to a computer the image quality is very poor, it can be used with a computer as the second screen in meetings
The HDMI cable is therefore so strong and device so small indeed if you attach the cable then the projector is losing its position
The switching off is hard holdon switch to the right Which is crazy, you can only command a sleep state from the remote Which is quite nerving When You Want to shutdown
Otherwise its a perfect device for this price. Goes with walls or on the ceiling
