LUMI’s PLB-M0544AI Smart Flip Down TV Ceiling Mount is a perfect choice to save space or for room with low ceiling. A quality motor holds TVs up to 32" ~ 70" and lowers and retracts TVs smoothly and quietly, completely controllable by remote or Tuya app (AI series). A balanced mechanism prevents any ceiling vibrations when the TV is in motion. There are convenient memory settings as well — a brilliant choice for public or home TV viewing installations!
