I bought one of item one week ago. I feel better now than before. My eyes, shoulder, face now relax. Both arms rotate horizontally 360 Degree (180 Degree in each direction). Easy to set up. Supports monitors weighing 4.4-19.8 lbs. per Monitor. Gas spring hovering system gracefully adjusts monitor height. I got everything which was said in product description. Great conception and output is awesome. Highly recommended for all.
What a great product! Even I could install it. Find a stud in the ceiling, drill a pilot hole, screw in the bolts. The rest is up to the projector. The Atdec Universal Projector Flush Mount swivels every direction to fit! Don't let the install manual confuse you this was a easy product to use!
