The poles are very sturdy, handsomely designed. The extend of the adjustable height is amazing. The top has small walls on all sides, with a protective rubber inside the edge, there are some openings on some of the sides that allow electronic cables to flow through. The best part is the top can be tilted to a very large degree, not only catering people's preference, but if it is for projectors, it will correct any vertical distortion that a keystone technology can not.
