​As the company's purchasing manager, I always repeatedly select from various conference equipment, trying to find a truly efficient weapon for the team. Last week's crucial customer proposal meeting almost became our Waterloo - the projector preheated slowly and the color was dim; the connection cable was like a maze, and the laptop interface could not be adapted. The precious first impression was almost consumed in the rush. At that moment, I made up my mind: I must inject fresh blood into the conference room.
