The first 5 months were good, it did need to be readjusted often, which is difficult as it is mounted on a high ceiling, but in the end it turned out that this is not the only mount on the projector a tripod (3 holes on the projector) the plastic case of the projector is broken. I would not recommend buying a bracket that attaches to 3 points on the projector rather than just 1.
