this motorized 150 '' screen be significantly cheaper than other comparable screen and the Prime Shipping from Amazon be fast . it have some good feature such as a wireless remote that allow the controller box to be mount above the drop ceiling and it be much lighter -lrb- allow for smaller anchor bolt -rrb- than other screen . my main problem be the curl left and right edge , slow motor and the poorly install bottom rail . Make sure you have the ceiling height -lrb- ie . at least 10 foot -rrb- if you be go to use it in a conference room setting . a 8 foot ceiling will cause problem .
