Note that the shield claims to block droplets, but not aerosols. Aerosols will go around any shield. Even this shield with some loosefitting fabric only blocked ~10% of aerosols. Making it tight fitting with an elastic band improves it. But really what would be much safer is surgical mask material or N-95 material that is tightfitting.
I do think that appearance is critical, at least in developed countries. In my experience, most people use only cloth masks, which block about 1⁄4 of aerosols. Moving to a surgical mask blocks about three quarters, which is an enormous improvement. There are concerns about long reuse of mass that are designed to be disposable, but they are doing UV treatment, and an easy thing is just putting it in an oven at about 80C for 45 minutes. A compromise could be a surgical mask underneath an attractive cloth mask, which is still easier to breath than N-95. Surgical masks seem to be easily available, and some are even attractive.
