First class Rolls Royce gun. The workmanship is "high quality", the system works perfectly. The 27-inch 4k LG display is perfectly balanced and easy to maneuver with one hand. I bought a laptop arm extender that added 3 inches to the height and about 9 inches to the reach. The laptop now protrudes over the front of the table and can be used regardless of the table height, while sitting or standing. Display and laptop cables are never connected to anchor points, and flexibility requires cables of different lengths. I have a 27" display and a Mac Book laptop floating above a cluttered 36" x 48" desk that is up to 23" high. up to 40". Sockets for fittings are attached to the wall under the table top with a single hanging cable.
