out of the box , the instruction be nearly incomprehensible . after I get it mount it be fine . it do everything I need it to do . I raised\/lowered it probably 2x a week for less than 3 month and the motor go out . the screen just plop all the way down and would not raise . as mention in other review , it cost more to ship the product back to FAVI for repair than I pay for the screen itself . I end up open up the case to try to fix it -lrb- stupid on my part -rrb- and make it 100x worse . I hope the motor would last longer than 3 month , so I will not be buy anything FAVI brand again . I reach out to customer service , so depend on what they say I may change my mind .
